Hong Kong has become a Special Administrative Region of China and has it's own justice, education, and political system (mostly). I think it would be a great idea to have several of these regions across the us to "beta test" different policies to see whether they would be good or bad. Changing a policy or law of an entire nation is hard and risky; trying these things out in special regions, where you have a known trial period, would allow much faster innovation in the political space.

"I think we need a way to have a faster iteration cycle for trying sociopolitcal ideas."

One of my personal hopes with Basic Income is that it addresses this issue by providing a safety net so that people who's livelihood relies the existence of the status quo can be liberated from the incentive to keep the status quo. For example, our government creates a Department for Homeland Security to address threats. It employs thousands of people. What happens if the threats go away and the department is no longer needed? Suddenly thousands of people are out of a job. That's thousands of people with an incentive to keep the department in business, which requires threats to our homeland security. Multiply this example across not just government institutions but private as well. People have an incentive to keep their gravy train running, even if it does irreparable harm. We need to remove this incentive so we can have faster iteration cycles, not just for socio-political ideas, but all ideas. Hopefully, a basic income can remove these perverse incentives by giving people a safety net. They're not afraid to lose their job, or move on from a shitty job, because they know they and their family won't go hungry, homeless, or without access to medical care.
