It solves only one of multiple problems new generations of cars (EVs especially) are facing

As an EV owner, I'm not sure what problems you're referring to.

Sure the infrastructure has a bit to catch up, but even without infrastructure, we're completely fine to use our EV for 90% of our commute (and our ICE car the other 10%).

But if density -- thus range -- were to double, infrastructure becomes even less of a dependency.

It's the main problem, as far as I can tell. I guess charging / "pump" time is an issue for cross-country road trips, but my personal needs would be entirely met by home charging.

Home charging isn't a thing for vast majority of car owners

Anyone with a house and an EV can do it. I don't have an EV yet but some friends just stayed for a week with a rented Tesla, and charging it up in the garage every night worked great, even with just a regular 120V outlet available.

> Anyone with a house

So how many people is that? Don't estimate house ownership or house rents on your circle of friends. What about cities, apartments with no means to install chargers? World is not urban sprawl where houses have garage and power available for charging cars.

70% of Americans live in houses:

Got it, world is America.

Also, the way North Americans are developing their dwellings and neighborhoods/suburbia is absolutely horrible

As of 2019, 53.3% of Europeans lived in houses: https://www.weforum.org/agenda/2021/07/flats-houses-types-ho...

"In 2008, it was estimated that six out of ten Japanese lived in single-family houses." https://en.wikipedia.org/wiki/Housing_in_Japan

I'm not going to keep googling this for everywhere but in developed countries at least, it doesn't appear that "home charging isn't a thing for vast majority of car owners."
