Terrible solution to an fake problem.

As an alternative reason or explanation for why taxing "land" instead of property built on the land:

The idea is to tax based on the //potential// value of the area to society, so that realizing that value to society is incentivezed. I suspect a real application of this would examine the difference in value to society and apply more 'incentive' (tax proportionally more of the missing value) the further from actual value to society a piece of land is.

How does this not end with all existent small owners being strong-armed into selling out to capital-heavy investors who can afford to build 20-story towers? Or is the point that it explicitly does not protect them, because they are "under-utilizing" the property?

I'd expect that such a policy would result in a lot of cultural churn, and homogenizing of communities to the point of losing any sort of interesting historical character. How can you have history, when everything is being bought up and redeveloped every (x) years because the previous owners can no longer afford the taxes on the "improved value". Everyone becomes the victims of everyone's success.

When "historical charachter" and entrenched interests are making cities en masse completely unlivable for anybody but the top margin of society, we have a serious problem that needs solutions. "historical charachter" is a pretty shitty reason that people should go homeless

I'm confused why you put scare quotes around "historical character" -- it's a real phenomenon and a real concern. There are places where historical character is what drives the demand so high to start with. Sure, you could fit more people into the historical district... If you knocked down all the historical construction and basically removed all charm that's attracting people there in the first place. And one could always invoke tourism into this argument also. Those same districts also tend to be the ones that tourists want to see, precisely because it's different from what they know.

because its often a canard in many areas for "no new development so we can artifically maintain a shortage, and keep our property values sky high".

Sorry but your property values and neighbourhood appearance shouldnt be winning out against people literally being unable to live inside cities because they have comitted the crime of being too poor.

I think there's a lot of secondary effects tied up in your statement that would not necessarily unravel the way you would wish them to. Ad absurdum, I don't see how it results in anything other than assigned, identical housing.

Because, even at a fundamental level, someone will always be willing to pay for something more than the bare minimum. And as long as that is true, there will be stratification. And that stratification will price individuals out of an area.

You are the one reducing it to an absurdity here, but the reality of the situation is people below the 90%th income percentile are being priced out of cities entirely, not just select areas, not just "historical" areas, entire metropolitan regions.

This needs to change, and I'm sorry if it means some property owners get huffy about actual affordable housing getting constructed.
