With Georgism, the government doesn't even need to track how much you make or have in your bank account.
I also wonder if practices would emerge to make it impossible to know who to send the tax bill to.
Well, you could just publish the list of taxes due and make it the landowner's responsibility to pay it, seizing the land if the taxes aren't paid.
I don't think the government would really have to care about who owns the land, as long as the taxes were paid, right?
Not advocating Georgism, necessarily. I just don't see this issue as being a real problem with the idea.
Sounds like it's Socialist for land, but free-market for everything else. Who knows whether that's good or not, but it's at least a different approach and more interesting than the standard "Progressivism driving the speed limit" that we're used to.
