Except that's not how Georgist tax structure is decided, it is 100% of the land's rental value. If you want a good overview I recommend this exhaustive and data-heavy series of articles: https://gameofrent.com/content/progress-and-poverty-review
Okay some things don't add up. You can't have a Georgist tax as a single revenue source for the government and calculate it off something other than what the government needs for revenue. Either you calculate the Georgist tax rate on the unimproved land value, you add other taxes to government or you slash and burn through government spending to deal with the capped revenue. It's living in fantasy land to say Georgis…
I agree there are some other things you can tax. I presume those are also taxed at precisely the economic rents they create? My point is that government needs some sort of tax with a knob that they have the ability to tweak upwards or downwards based on shifting revenue needs. It seems to me the only things in a Georgist system are taxed at precise values and fail to give government that knob. Do all Georgist societies have some sort of services cap because their tax revenues are capped?
