I guess i forgot to mention a few things.
yes, obviously, you're right - if energy prices surge from the socket, then that goes hand-in-hand with creating synth fuel as it needs lots of energy.
however, a few things to adress here imho. without a single doubt, the process of making synthetic fuel will become vastly more efficient in due time.
Here's the thing: it won't. The efficiency estimations provided weren't for a 'current hypothetical lab process', they are decent estimations for a mature process - and they are not expected to go down by much between say, now and 2050. (
https://www.forbes.com/sites/jamesmorri ... hey-could/). The reason for that is rather simple: the energy efficiency in the first steps is already rather high and there is little room for improvement. The losses are mostly because many steps are needed (so they add up), and because the low CO2 concentration in the air inherently makes direct air capture an expensive and energy intensive activity. However, the real big loss is, ironically, the ICE itself. And that is also the most mature piece of technology in the chain. Yes, we can make them smaller and out of cheaper materials, but in terms of efficiency there's not that much to gain there.

However, if these refineries build their own power plants - through solar panel, wind turbine and water power - then they will NOT be dependant on the socket,
as they provide it themselves. Obviously the issue here is providing ENOUGH energy to 'fabricate' synth fuel.
However, if - and it's not an If, it's a guarantee - energy prices surge due to there being an insane demand to charge EV's, then EV's will become more expensive to run and drive.
You are again assuming some kind of non-existing asymmetry between electricity use for synfuels and EVs.
In your argument, when EVs need electricity, prices surge and everything is expensive. When SynFuel needs electricity (and needs 5x more), prices will drop and it's seemingly easy for Shell to build huge, cheap solar farms. Obviously, that's not how it works:
- Shell and Vattenfall are competing for the same resources (solar panels, windmills). There's no reason to believe that Shell can buy them substantially cheaper than Vattenfall.
- Even if Shell would have their own farms separate from the grid - if the price difference between 'their' electricity and their own electricity are substantial... they'd just hook them to the grid and sell the electricity with a higher margin than they could on synfuel.
- Legislation doesn't matter: if countries can give tax breaks on synfuel, they can do the same for EVs, and they can equally decide on tax raises for either. If you cannot make your case without legislation, you don't have a case*

And we will inevitably fall to an equilibrium to where it doesn't matter in driving an EV,
or driving a Synth. All that will matter is it's 'economy' and practicality.
Except that you are continuously omitting the displacement effect that I highlighted several times. Even if prices would be equal, given that due to efficiency you can choose to:
- Have power 5 BEVs with X amount of electricity
- or, with the same electricity, power 1 synfuel car (and rely on fossil for the other 4)
Why would you chose the second option? It doesn't make a lot of sense to actively increase energy use, in a time we should be decreasing it.
As another example, let's consider a more macroscopic scenario. A country, hypothetistan, has a total electricity consumption of 3000 PJ/y, currently all fossil; in the coming years they plan to convert 600 PJ/y of their electricity generation to renewables. Furthermore, the country requires 450 PJ/y in petrol/diesel for road transport. They want to replace fully the transport fuel by an emission-free alternative.
If we assume an average engine efficiency of 33%, the 450 PJ/y of fuel is actually 150 PJ/y of 'transportation energy'. They can opt for BEVs (65% efficiency), which would require 230 PJ/y of electrical energy. Or they can opt for synfuel (15% efficiency), which would require 1000 PJ/y. In case of BEVs, the total electricity demand increases to 3230 PJ/y. Still, after installation of renewables, their overall fossil use will decrease (to 2630 PJ/y). In case of SynFuel, they will need to
increase their fossil fuel electricity to 3400 PJ/y to even meet demand. Sure, they're getting rid of the fossil transportation fuels, but in effect all of the fuel they got off the road now goes into the big burner.

And let's face it: EV's are going to take longer to 'refill' practically than a combustion vehicle.
Liquid fuel is always more practical than battery power.
Did I ever deny that? Quite the contrary. I highlighted several times that there are certain niches where synfuels make sense. But we're talking about the average consumer car right now, and the average commuter or short-haul transportation firm can do perfectly well with charging overnight, and maybe during their lunchbreak.

And F1's running V6's and (was) thinking about 4 cylinders because of a 'green' image.
"green" indeed. It's greenwashing still. Sports are a luxery, and as such the "green" thing to do would be to cease.
Now, I have no such intentions. While the per-capita footprint of sports is huge, the total footprint is relatively small on the large scale of things, and within F1, the footprint of the cars is small compared to the whole circus around it.
I can live with that. But I'd rather see them be honest about it, than to go through great lengths for some greenwashing. Especially if that greenwashing is paired with claiming that what they are doing is road-relevant, while it's not.

ANY car buyer would prefer to have a Audi A6 or a Mustang with a V8, over a 3-cylinder turbo. And any Ferrari buyer or Lamborghini buyer will gladly have an exotic V12 over a 4cylinder or a full electric.
I don't. Beasts belong in the arena - on the road, I want something that does the job with minimum impact.
* with legislation here, I mean regular taxation/tax breaks. There is an exception for what now is called 'true pricing', but is otherwise known as including the costs of externalities - that is necessary practice for fair competition
