> making cities not requiring cars to live in them is a pretty good plus, no?

Some cities are doing this, but they're not the ones attempting 15-minute cities.

The 15-minute cities are doing things like putting up barricades to make driving more of a pain, without actually making them more livable in those confined locations.

Filtered permeability (which is what I think you're referring to re: barricades) does itself help you live without a car nearby. It cuts down on through traffic for cars in those areas which makes it safer and more comfortable to bike there.

Exactly, why should cities optimize for people who have to drive into them, vs people who already live and pay taxes there?

Examples?

I live in Europe, 15-min cities are quite standard here so I don't really grasp this American issue.
