You will never convert me to your way of thinking. Land taxes have a long history of being used by those in power to take desirable land from those who have it and invite corruption. You should only have to buy your land once, not rent it from the government. The government has plenty of other ways to collect money and isn't the least bit afraid to use them. I'd prefer to be secure in my possessions, thank you.
The land will have to be managed. This system of making land so expensive is unnecessary and put everyone in so much debt they can't get out of it. A total reboot is in order.
