A 15 minute city is not an evil on its own - I already live in one, and I like it, because I'm fucking lazy and hate driving. It's not a 15 minute city by design, though. It just turned out that way, over a century ago.

The evil comes when you try to force people to remain in that 15 minute bubble. Nothing stops or pressures me not to drive an hour away if I want to. There's no toll gate punishing me for leaving the bubble.

If they want 15 minute cities, they should use the carrot and abhor the stick, because the stick will just turn people like me against them.

I forget who it was on this sub who recently described me as disagreeable to a potentially pathological level, but I suspect they're right, because I feel motivated to oppose people on matters I agree with just because I don't like the way they're doing it.
