I get you're being sarcastic here but it's clear that the market hasn't been a total success with EVs. They require much more charging infrastructure before many will consider buying, but the EV infrastructure won't be built until there is demand for it. This is a classic example of where a government can step in to tip the scales and force a desirable outcome.
So why ban instead of subsidize? (in the general case, we all know that states like NY love to ban things)
Rooftop solar got cheap enough to be not quite viable and then took off like a rocket with government subsidy. If people could install chargers at a negligible net cost to them you'd see them everywhere as landlords and house flippers jump to "check that box".
Because climate change is an emergency? Because it sends a stronger signal? Because it's what in line with countries across the world (and California) are already planning?
