I charge my car off of a regular outlet outside in a very cold climate, and charging like that will actually likely make the battery last quite a while. The only way to find out for sure is to wait, but it has been 4 years and the battery hasn't lost any capacity. My car also has a 320 km range, so even in your scenario, if you charged 50km away and came home, you'd still have 270km of range.

I think you may have given too much weight to FUD about EVs from companies that would like to see them fail. I've seen a lot of concerns posted online that just don't practically matter, once you actually try it. There's also some really nice minor things about owning an EV, like not having to breathe in toxic fumes when walking around the car. Especially nice if you have kids that are right at the level of the tailpipe.

It is also fine to wait a bit, of course. In my area chargers are springing up in lots of places, and I think we're not far off from a tipping point away from ICE cars, which will spread even to rural areas pretty quickly when gas stations start becoming unprofitable.
