Georgism and Distributism is interesting but short of a plan to actually transition the tax infrastructure in that direction this article reduces to an unactionable history lesson. Still worth reading, but not powerful enough for those who want economic change. I'd argue that transitioning is an extremely hard problem. The Georgist system taxes property at extreme rates. In particular, the taxes on property ownership…
I think you might misunderstand Georgism, or maybe I did a poor job explaining it. Georgism does not propose taxing improvements (buildings etc), only the actual land. So many peoples tax burden would be decreased, and if the bank owns the land as in a mortgage, they are the ones paying the tax, not the people taking out the mortgages.
Once you add the taxes for other jurisdictions of government I can see taxes reaching 30% of total mortgage value. It's fairly clear to me that owning land is extremely expensive in a Georgist society that needs to generate the levels of taxation that fund current government. If land value tax replaces income tax it needs to be fairly large, taking over 20% of mortgage value for just federal costs.
Some number of homes are owned outright and no longer have mortgages so the mortgage number may be a bit misleading. If we account for this we might get to a level that suggests 10% of mortgage value in taxes federally, raising to 15% of mortgage value when accounting for other levels of government. Such numbers suggest you'd need to be able to pay for your current property with an 8-year mortgage in order to pay the Georgist taxes on it.
I think a modern society that kept existing levels of government spending would see widespread downgrades in housing quality in a Georgist society.
