That solution isn’t really a solution.

The minimum cost to live in each jurisdiction

There is no clear objective way to measure that. The absolute minimum to stay alive would technically be just enough for the single cheapest available food, and just enough water to avoid death (maybe not even that, if it’s legal to just drink out of a river). I’m sure that’s not what you meant. But anything beyond that has to consider the incredibly subjective quality of life question. So what you propose is really just a goal, not an actionable policy.

If you can impose a fine you are a jurisdiction and it is your responsibility to implement

That’s a way bigger headache than I think you realize. At any location in the country, you could be fined by the federal gov, state gov, other states if you do business there, multiple levels of local gov (county, city, etc.), even your HOA might be able to fine you. But that all depends on thousands of existing laws and precedents.
