Georgism was proposed in a time before we invented zoning, which was a system explicitly motivated by racial and class segregation. The Supreme Court case that made it constitutional is explicit about wealthy land owners having the right to exclude the poor from living in apartments nearby.

So we need additional correctives to the additional injustices that capitalism has invented since Henry George's time, like our NIMBY-promoting land use decision system. We could, for example, adopt something like Japan's more federal system.
