Do you wanna get together with a bunch of like minded people, find a city somewhere where you can vote in new leadership and destroy the police department, and see how it works out?
The hippies tried their version of that back in the 1960s with Vermont, and it turned Vermont into a substantially more pleasant place. Some people tried it in Aspen (read Hunter Thompson's proposals for how he wanted to reform the police department and what the voters did and how it played out; it is fascinating reading.) The libertarians tried it somewhere in New England and somewhere in the Southwest, more recently, and their philosophies in practice were an utter failure.
I am asserting that your solutions will not work in the real world. If you want to prove me wrong, you are empowered to organize and find a place and make it happen and run the experiment. People are actually doing this with non-destroying options like sending mental health professionals on mental health calls, and it's working well, so sure give your thing a shot.
