All good points. I haven't encountered an implicit deal breaker/an issue impossible to mitigate yet while thinking about it. The devil would be in the details.

I would need to do some deeper analysis to fully convince myself that this could be applied in such a way that it doesn't screw over retirees nor drop an economic atom bomb on every major urban area. Seems more reasonable than a lot of wild overhauls I've read about though. I like it more than the "get rid of all taxes except for sales tax" idea.
