The incentive is already there, it’s just prohibited because of zoning and building codes many places. All the government has to do to fix this is stop getting in the way.

Yeah. I think what these people mean usually is that the phrase “separation of church and state” isn’t in the Constitution, which is true. They heard that somewhere and repeat it. Maybe that West Wing episode where Charlie does a bit about it.

Yes, all ancestral land claims are ultimately at least a little bit silly.

There are lots of good ideas out there, I’ll just add some that are pretty niche:

1. Anything that is legal to do for free is also legal to do for money.
2. All laws must have a justification for them written into something like a preamble. If the justification turns out not to be true, winning something like a basic law suit against the law is all that is needed to have the law struck down. No need to wait for legislators to pass a repeal bill or for a very specific case to make its way to a supreme court.
