Realistically, you'd need a lot of political capital and a desire to move the entire state construct in this direction

Create a blockchain that works so well it takes care of this on its own. I can only see this working if all the leasing and expenditures are done on block-chains (or better) under smart contracts. The state as we know it has got to change too, paying the state is sickening thought to me. The idea of paying smart contracts might be something we can tolerate.

A Universal Basic Income would be ideal here too so people without an income would always have the right to occupy and farm land too. Smart contracts could ensure this money is not mis-managed.
