>In a dense location, each business can be reasonably expected to build parking... because the city requires it.
Well, no, thats my point. A dense location... is dense. There’s not much room for n parking per business, at least directly where the shop is located. You meet the requirement by doing as the article does: destroying dense locations and forcing them to be sparse. Pretending that they live in the middle of nowhere, when in fact they’re in the heart of the city.
Parking garages/lots (lots of parking, shared by all stores) is a clearly more ideal solution: its much more compact. And there’s no real reason parking has to be located directly next to the businesses themselves; just nearby enough to make walking (like, well, any shopping mall)
So then you have the question of who pays for it — in a shopping mall, its built in by the mall. In a city designated shoping center, its built in by the city. But those are totally pre-planned situation. In a more organic environment, where parking minimums are meant to operate, it would either be a collective decision... or its independent of the businesses, and expanded as necessary, as any private garage works. And I’ve personally seen examples of this situation in LA, chicago, mumbai.... and probably any city that manages to exist without minimums.
The only way you can believe that parking has to have a minimum is if you believe parking must be free. But thats nowhere near true. In most cities, but not in a mall, its not free.
The freeloading problem in a dense location is trivially resolved by looking beyond the individual businesses, and realizing that parking itself is a market.
And the belief that its absolutely required is trivially disolved by... realizing parking minimums are already not the default, and so pretty much any successful city/area will constitute an example of it not being a necessity
Home depot/ikea are self-incentivized to build parking for themselves, because regardless of minimums, they tend to carve out a huge plot of land for themselves and exist independently of other businesss. They don’t sit in dense locations by their nature, and I don’t think you really want them to, and they barely share parking by their nature.
