That assumes taxes are there to raise money. They're not.
Taxes are there to raise armies, not money. Government doesn't need any more land to do its work. Nor does it need money, since it is the currency issuer. What it needs is manpower. That manpower has to be released from the private sector who would otherwise employ them.
Therefore the most effective taxation is one that leads to fewer job offers from the private sector of precisely the sort of people government needs to hire to do its work.
Land and property is the least effective taxation that requires a large amount of fungibility in the economy to deliver the people government needs to hire, and is the least countercyclical to the business cycle.
