So since this is HN... is there any way to get to an MVP without having a sovereign state to experiment with?

Generally, any communal institution either develops rules and mechanisms to prevent freeloading, or has an authority who acts to prevent such. Almost all of them succumb to a "Tragedy of the Commons" dynamic in terms of some aspect of quality of life.

That said, there are some institutions that are identified as being communal that last and even prosper somehow.

Many also cite things like the Cabrini Green projects as an example of how removing the stake someone has in society by guaranteeing their rent/income is somehow inherently dehumanizing. To fully address such a hypothesis, one would have to control for factors such as social class and social stigma attached to such benefits.

The Sea Steading Institute aims to lower the barrier of entry to creating your own sovereign nation. One of the core ideas is that if we have lots of small nations people can do these experiments and find out.

How close are they to a "demo version"?
