Okay, let's assume land is expensive and you do need the parking lots. Georgism just tells you, please use the land more efficiently. Underground parking or a multi story garage become profitable as they reduce the amount of land being used and therefore reduces land value taxes you have to pay. Ethical tax avoidance!

You do know that you're substituting expensive parking for cheap, right?

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.
