Ground rent creates more wealth than our present system. Vastly more.
So the first nation to adopt it will rapidly pull ahead of other nations.
But it might take a long time. Human minds take a long time to adopt big new ideas. Big ideas, like free speech, or the scientific method, or ground rent, can take centuries to be accepted.
And maybe humans can never be persuaded. Society has been built on theft since civilisation began. And taxation is simply "the alpha male takes your stuff": this is hard wired into our primate brains.
But do not despair. It doesn't matter if we don't understand it. The more efficient system will happen anyway. Because humans are becoming slaves to a more intelligent master.
