It seems like unlike most exciting economic ideas that economists swear by but governments ignore, Georgian Land Value Taxes should be fairly doable for a private development company to test.

They would have to buy up a large area of rural land at a cheap price, and then rent it all out with a contract that specifies how the rent is reassessed each year based on the estimated value of the land.

If they are right that LVTs are one of the best ways to encourage development of the land this should be a very profitable venture as rents will quickly rise.

It's disadvantage is this can't be used to replace other taxes (except for municipal taxes), but we could use the profit earned by the company to estimate the minimum amount we could reduce other taxes by.

I assume the difficulties with this are:

1. Buying up rural land in an area people might want to live in.
2. Rezoning the land
3. State laws making it hard to develop the property
4. People are wary of the weird contracts so keep away

On the other hand you might see economics fans moving there on principle which will help give it a boost of educated well off people to get started.
