Yes. The commons morally shouldn't be owned by anyone. They can own the building on top of the commons, because they built it, but not the commons (land) itself, which they had no role in creating. If we want to invent the concept of land ownership, then people should pay rent to society for the privilege of monopolizing a slice of the commons (and the privilege of soaking up a larger proportion of the benefit of public investment in the armed forces, police and public infrastructure such as roads).
It’s property value + land value. Even if I make 0 improvements to my property my tax seems to go up every year. It’s because the property value has gone up even if the improvements haven’t.
Yeah that's a property tax, not a land tax. Far from ideal because it punishes people for improving the land that they're occupying, which is the opposite of what we want to be doing.
I guess the affect really depends on where you live. Where I am land is really expensive. So even if you owned an undeveloped piece of land, your taxes would still be significant.
But I see what you’re saying. In a lot of places the land and taxes are relatively cheap.
