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.
