You can't push demand down people's throats even if they are receptive to EVs. Where are renters going to plug in their state mandated vehicles? Homeowners who don't have a secure place to plug in? People who can't afford electrical upgrades? Sucks to be them, go ride a bus?

There is still a used car market ? Alternative to not buying a new cheap gas powered vehicle is not public transit

There is a gas-user density threshold below which stations stop being viable. It will be interesting seeing the map of gas-station deserts develop and expand over the coming decades.

As a daily driver of hydrogen fuel cell vehicle I experience that today, if I can manage with just 45 pumps in all of California some constantly broken down, and still do 15,000 miles/year it should be fine even if many pumps disappear.

Gas stations may become primarily supercharger points, and pump maybe in one corner as a legacy, i doubt it would completely disappear as long as old vehicles still ply the roads in numbers.

From public transit to government subsidy for people economically unable to make the change there are many policies we can effect to solve this problem. Indirect subsidy of Gas[1] should not be one of them

[1] Without a carbon tax on emissions we are all already effectively subsidizing the costs of climate related economic impact of floods, droughts, forest fires so on.

Used car prices are already skyrocketing. And with all the manufacturers having already stopped making their cheaper cars, it's only going to get worse. Add in forced EV adoption, and demand for used cars will go up even higher.
