I work on them for a living. You either double the current or double the voltage, if you want to double the power. Doubling current means the copper carrying the energy has to be twice as thick. And they can't step up the voltage much more at local levels, usually not at all.

Car chargers for the home run on 220V. Are you really trying to say that the current grid cannot supply that voltage to houses?

No, you are confused. I'm not talking about the wall outlets at your house.

I'm not confused. Home charging for an electric car can be done with a regular 110V outlet, but it is very slow. If you hook it up to a 220V then it will charge overnight and those are common home outlets for electric stoves and dryers. Nobody is looking to put the "quick charge" stations in their homes, those are and will continue to be commercial applications.
