You really only have 1 problem (aside from perceptions), but it's a real one. You need to be able to charge at home, and it sounds like you probably can't do that. You'd be stuck on trickle charging (3 miles of range per hour on the charger), and even that's questionable.

The car will keep the battery warm whenever it's plugged in. If you take care of the battery (rarely let it go all the to 0% or 100%), it will easily last over 100k miles, and probably to 200k. When it does start to wear out, it's not a hard cutoff- just like your phone, you'll notice the capacity (range) starts to drop.

FWIW, there are very significant federal rebates/tax credits in the US for EVs. That specifically includes upgrading electrical service to support an EV charger. But given that you said kms, I have to assume you are in a different country. Many have their own incentives, but you'd have to check into those yourself.

I get the old house rural life. I wouldn't worry about the lasting 7 years right now. That being said driving a relatively efficient car for a couple decades is definitely environmentally friendly by comparison to getting a new truck every 5 years. Probably not too far from buying a new EV every 7 years once you add the embodied energy.

In a few years things will come around so make sure you've upgraded your electrical panel by then.

I had a 87 corolla for the longest time. I sold it to a teenager a over a decade ago and I still see it rolling around town. Great car if you are only worried about going a-b and don't need fancy things like usb chargers or A/C.
