An interesting supposition. The United States was founded as a limited government Republic by the recent descendants of people fleeing an oppressive central government. In fact, there are very few examples of an oppressive central government with a large intrusive bureaucracy ever becoming a limited government with great individual freedom.
As the United States becomes what everyone fled when they came here, perhaps the only way in the future we will ever again see that type of political and social system is when mankind goes somewhere there is currently no government. Then we can start again from scratch. And we’ve pretty much run out of real estate matching that description on this planet.
And the Moon is a harsh mistress...
