The issue here is that for those things you suggested to exist we would inherently need to reduce parking as part of the change in regulation. Parking spaces are currently taking up the spaces that those amenities would be built, just as you described.

Unfortunately, NIMBY fools hear “reduce parking” and completely turn their brains off to screech about it, without ever considering the rest of the proposal and what it would do to benefit the community, simply because it makes them change their habits and they don’t want to.

Like, yes, there will be parking shortages, but that’s kinda the point so that people have to utilize alternatives instead.
