Luckily you don't need to maintain electric cars at all.

You do. But keep in mind they have way less parts, moving or otherwise. Spark plugs, cables, the entire engine cooling system, fuel pumps, all of that is missing.

It boils down to: battery (big unknown, but seem to be holding up surprisingly well), engine (incredibly simple!), no transmission or a very simple one (Nissan Leaf has a single gear), inverter, charger, brakes, and the standard 12V battery you find in all cars (which doesn't have to drive a starter motor, so should last longer).

Wow, electirc cars are so simple it is surprising that so few companies make them! The moving parts in a car are pieces that 1) have multiple manufacturers and are relatively cheap to replace, and 2) can be replaced by a wide range of repair shops so that competition can keep a check on the overall replacement costs. What you left out of your electric car list are all of the specialized electronics and only-for-this-car equipment that are all very expensive to replace and will all only be supplied by the manufacturer. The idea that you can just go online and shop around for an inverter for your Tesla or run down to the auto parts store to pick up the right 12V battery is laughable.
False comparison. Your gas car also has specialized electronics, namely the ECU, the ABS system, the SRS system, which are all needed for the car to be operational. Good luck finding an aftermarket ECU for your car.

There's no more "only-for-this-car" equipment in an EV than in any other car; the main difference is that with so many models of gas cars made by each maker, they reuse a lot of parts between models, so there's economies of scale. In an EV future, the same would be true for EVs. You're not going to swap an axle from a Chevy into a Honda, or from a Honda Civic into a Honda Ridgeline, so even here it's limited. And you're not going to swap a door panel from a 2017 Civic into any other car at all, or from any other car into that one; those are only-for-this-car items; every car has those.

There are lots of aftermarket ECUs [1]. Usually only performance tuners buy them, but there's no reason you couldn't get one for other reasons. That said a junkyard ECU is going to be a much easier fix.

Your aftermarket ECU won't pass emissions tests in most places that have them, so this really doesn't exist for practical purposes. Aftermarket ECUs are for race cars.

As for the junkyard ECU, why do you think that won't be also true for EVs?

You can usually choose different maps with aftermarket ECUs, there's no reason you couldn't load one that passes emissions tests.

I've flashed my own car's stock ECU with a tuned map, but it's easy to load the original one back on.

Anyway, this is a stupid argument, I hardly think that emissions tests will be a reason you can't put an aftermarket ECU into an electric car!

FYI Generally an electric "engine" is referred to as a motor.

My hybrid actually has two independent liquid cooling circuits: one for the ICE, one for the electronics.

But other than that nit, I agree with your argument.

Battery cooling is also a factor that you shouldn't ignore
