They are simpler to fix and cheaper to fix.

I think you're ignoring the big problem, the battery. When that goes, it is a big deal to replace, and mucho expensive.

This, in my book, is an unknown. I though Tesla said batteries are getting better 10% a year / 18 months. And I'm sure replacing bad cells will be cheaper than the whole pack.

Someone smart will make a machine that will help me test good cells from bad. Someone else will be ripping good cells out of junked cars.

Someone else will be doing hire purchase on batteries - £200 a year, battery pack replaced every 2,000 charges? Something like that? Sounds fine to me.

A battery is on the order of the same cost as fixing an automatic transmission (which basically all US cars have--most of the US can't drive a stick anymore).

And, in terms of labor, a battery is WAY easier to replace than a transmission.

There's an even bigger bonus that in ten years the battery pack will probably be cheaper and have a better range. So while the replacement may be expensive the car will be dramatically better afterwards.

And you can recycle (sell) the battery pack after you replace it. What do you think is going into Tesla's Power Wall? Why do you think they're pushing leases so aggressively?
