Land-Value Tax seems roughly right to me, but I feel like they could be generalized to graph-centrality taxes:
It's not that we don't have enough land, but the value of land is really dependent on how valuable the land around it is (in a fashion similar to the value of networks in Metcalfe's law[1]).
So establishing the value of land is a kind of coordination game, in which people try to eke out centers of valuable land.
In a similar fashion, rare nodes central in a semantic network (such as domain names for very common words) have only value due to their connections to other nodes nearby.
Corollary: Land-value tax would make far less sense in a hyperbolic space: It's really easy to get from one point to another quickly.
Natural resources consumption taxes might still be worth it.
