Good article.

This is in some ways an old idea in new context, similar to the the classic "Land value tax" https://en.wikipedia.org/wiki/Land_value_tax .

Urbanists have some been advocating this tax as an alternative to real-estate tax because of the massively inefficient use of land since the automobile became popular and the urban sprawl became a problem as a lot of valuable land has been inefficiently used and allocated as parking lots and motorways in often in collectivised or semi-collectivized ownership.

This could also be implemented on a second level as "charter cities" could act as 2nd tier owners under the nation state and "lease" land to private owners in exchange for funding city infrastructure.
