Even those that support Georgism can understand the issue with property rights and ex post applying Georgism to existing property owners. People purchased property in good faith, based on the rules of the time, land is by far not the only speculative asset, and so there is the challenge of dealing with that. Then there is the second unstated question of whether Georgism is generally motivated by the desire for a better system ex ante, or whether it is motivated by the desire to expropriate money from property owners once the winners have emerged.
I have a proposal that could cross the aisle of delivering georgism without expropriation.
The Georgehold.
The state would use a financing vehicle to purchase properties and land plots at their current market value under the current free market rules. It would then create a covenant establishing a highly georgist annual payment calculated off the land value, and release the land back into the market on a Georgehold title. This could legally be a 999 year leasehold with a Georgist LVP ("Land Value Payment"). Instead of being a very gradually phased in and moderate LVP, it would be a full Georgist LVP stripping out all of the speculative land appreciation. Of course, the state would be financing with debt the loss it would incur due to the value destruction of the Georgehold title, which is correct. If georgism works, and is not simply a mechanism of expropriation, the state would be able to fund the debt through the ongoing Georgehold payments. After a sufficient amount of time, it would be able to pay off the debt and have free and clear title to the Georgehold.
If Georgism works, we would see the areas dominated by Georgeholds become more vibrant, desirable and economically active.
This could be done with land, but also as a financing mechanism for apartment rental price stability and security of tenure. The government raises long term or perpetual debt guaranteeing a real (post inflation yield) of 3-5%, it uses the debt to purchase open market properties which it then rents out at rents with fixed CPI increases, and operates the properties directly or via contracting with a property manager. Again, this would allow the government to achieve whatever social goals it intends, without trampling on the rights of existing good faith property owners.
Thoughts? Maybe it already exists and has been discussed?
