The most popular proposal (from Henry George) is to maintain individual land ownership, but impose a land-value tax that approaches 100% of the land rent.

The result is that real estate basically sells for roughly what it would cost to rebuild whatever is built on the land.

There is still a premium charged (in the form of LVT) to allocate access to desirable locations, but the revenue goes to the government/community instead of the previous owner. And the eliminating the incentive for land speculation should actually reduce overall costs.

I didn't say no land ownership. I said tax the gains of land ownership. Nothing changes about who decides what gets built etc.
