I've been driving an EV in the UK for five years. The charging infrastructure has significantly improved and continues to significantly improve. Could it be better? Of course, but that's been the steady trend for years now. Saying that no-one can switch because things aren't 100% perfect and ideal is just wrong.
Flats? I know two people with EVs and no off-road parking, and I fairly regularly see EVs parked outside on the road too. It's entirely do'able.

Myth 1.
