Sometimes the bigger challenge is "law repealing" rather than "law making".
For example, how do we get people growing edible landscapes in their front gardens if the "law" says the need a bunch of lawn?
How do those plants grow without toxic gick if the "law" says they aren't allowed "farm animals" inside the town limits?
How do those plants get fertilized if the town tells people they can't have honey bees and that they should destroy wasp nests if they see them?
(yes, I have family in a city that has done both those last two - they've even banned pet rabbits, although there are plenty of wild rabbits around.)
On the positive side of things, any actions that can improve local resilience - like encouraging rain gardens and swamp restoration for water management, and for open areas being turned into food forests (assuming you can find people to care for them so they don't attract bears) are great ways to permaculture an area.
