Tech billionaires want autonomous communities without taxes, government. What are the implications?

The movement by tech billionaires to create autonomous communities, ruled by their own law, without taxes, and fueled with cryptocurrency, is growing. The latest attempt is the Caribbean islands of St. Kitts and Nevis, where some residents are trying to block it from happening.

But the movement isn't new. There's already Próspera in Honduras. Other ideas they've floated include sending colonies of their peers to Mars or creating floating island communities, which wouldn't necessitate purchasing land from an existing country.

But what are the economic, moral and political implications? And can the plans work?
