However, you are demonstrating that Georgist "efficient land use" is not particularly desirable. (Moreover, "efficient" land use is rarely that important.)

Georgism does push towards a monoculture and a particularly horrible one at that.

For example, Georgism punishes someone who puts some open space between buildings, even though open-space is clearly a good thing.

As I wrote previous, Georgists confuse having an equation that they can "optimize" with having a useful idea on how to allocate resources in the real world.

Yes, Georgism lets you do some calculations, but that doesn't imply that doing those calculations is worthwhile. (This is a problem with economics as a field.)

And, no, the "witticisms" don't make your case. They actually argue that Georgists are dangerous fools.
