Isn't that what people have already collectively done in cities? It takes $2k/mo to live in Seattle. The land I live on is valued at 5x what the house is worth and I'm not allowed to build an apartment on it.
That's what we've outlawed -- we've outlawed all gas stations and supermarkets from raising prices regardless of monopoly. They have diverse ownership.
Tripling prices of TP so you don't hoard during a shortage seems less detrimental to society than locking generations of working class people from being able to ever join highly-productive areas.
I guess with a land value tax you can be sure the land is being used economically efficiently. As it is, the land is being used inefficiently. So I suppose itβs a market, just not an efficient one.
