I think 15 minute cities are great if you have everything to back it up.

This is just a tautology

I think water is great if it has two hydrogens for each oxygen

Even if you have most things nearby for day-to-day life but still need to travel an hour for any of: school, work, daycare, groceries, or even common leisure or entertainment activities, “green spaces”… Then that ain’t a 15 minute city.

Additionally, transit is absolutely included in 15 minute city concept - whether it be pedestrian, biking, bus, train, mixed-mode trips, cars*… It’s a holistic concept so of course these are all under the umbrella.

* yes even cars can be included, but in order for the others to be successful they are general de-prioritized in this model.

Edit: I’ll also add that I see “15-minute city” is an aspirational goal, and anything that moves us closer towards it tends to be good for the people that live there - and even if not fully achieved in a particular place, this type of hand-wringing about specific aspects in order to disregard the whole concept seems disingenuous at best.
