I came up with a scenario about why I thought this would hinder property improvement, but I think I solved it within the Georgian system:
Let's say Alice buys a piece of property zoned for 10 story buildings at 2mm/year LVT. She invests 30M and 3 years of construction into building a 10 story building that can generate 4mm/year in rent. It will pay itself off in 21 years plus start generating profit. Alice has specialized in being a great property develop but not a property manager. However, she is now TIED to this property -- if she lets it go up for auction, she loses the profits from her improvements. Sure, she can contract out property managers and eat into the profit, but this just increases the time until she can afford to build the next building.
In a capitalist system, Alice can sell the building upon successful completion and immediately profit to the exact degree the market thinks she improved the land's value. That capital can immediately go into the next project and allow better specialization of human resources.
However, I now suppose that the party who "bought" the land from the feds doesn't have to be the specialist who gets contracted to develop it. She can still be paid 30M upon completion and go straight into the next project with a different owner, without ever dealing with an auction.
I potentially like this system a lot, as long as it allows wealth and non-land property rights, and market pricing, but I do need to think about it more. Thanks for helping to explain.
