> This is distinct from a property tax in that it only measures the value of the soil it sits on, so doesn't punish the landlord for improvements. The value of the land itself is almost entirely outside of the landlord's control, it's determined by the community around it. As a result, this is one of the least distortive taxes.

When land value is taxed at a higher rate than property value, it creates a perverse incentive for landlords - especially those who don't live in the area in which they own property - to encourage blighting and sabotage the value of the land, while instead reinvesting this money into improvements on the property itself. That concentrates wealth even further in the hands of people who can afford to own these insular properties in otherwise "undesirable" areas.

Actively blighting a neighborhood to depress values and make it easier to purchase land for new properties (either on the market or via eminent domain) is already a problem, and one that significantly skews power towards the extremely wealthy and massively-capitalized institutions. Taxing the value of the land separately from the property that sits on it (and at a higher rate) would exacerbate this unbelievably.
