You would need a way to make local law not geopgraphically local but ideologically local. I would love to hear ideas on how you could ever manage that, but my proposition sacrifices some of the humanity potential (if you are voting STV for a local council in a town of 3,000, and have 10 members, in theory each member represents 300 people but nobody will personally know all 3,000 and thus is limited in candidate to whomever they do know, or worse, someone they take at face value like they do today). You lose quite a bit of democracy there, in that some people probably will not have a candidate they like - there are certainly more than 10 distinct political viewpoints in 3,000 people.
But I'd also think such systems would promote people to live with the like minded. If you disagree strongly with your neighbors... you are probably in a bad neighborhood for your own good and happiness. Surrounding yourself with enemies in your daily life provides a fulfilling life to few. But that goes down a deeper rabbit hole of people not considering nuance in where they life - they place work and profit ahead of all else, and will prefer a trash bin in the Bay Area over less lucrative ventures elsewhere they can have a more fulfilling life in general.
