That's very different from "stop letting them buy gas" - It doesn't punish people for continuing their current standard of living nor forcibly reduce it and it doesn't immediately destroy the value of gasoline passenger vehicles, in fact it may increase them unless charging infrastructure catches up in those places.

No they aren't (or at least that's not what your link says). They are banning sales of new gas-powered passenger vehicles but for the foreseeable future you will still be able to buy gas for your old beater, '67 Mustang, or red Barchetta.
