A metal/medieval/gothic/renaissance community where employees live on site. Similarly, Disney World, somewhat self-sufficient, also has some housing for its employees.
Cost: tendency to depend on profit not culture and accountability to the surrounding government's laws and taxes. Startup outsider capital investors would want their money back and then some, quickly.
Benefit: cleaner, quicker interface into existing society by being another corporation.
Establish metal townships on an island independent of other nation states.
Cost: economic isolation from limited natural resources and tiny volume of trade exports due to scale. Lack of available island within group's budget. Iron, meat, stone, grain and hardwoods might be very expensive commodities locally. Insignificant military protection. Chronic poverty.
Benefit: autonomy, exclusivity, strong isolation from modernity and crowds
Buy up adjacent country or ghost town lots in America. Smokey Mts might be a good pick.
Cost: initial lack of work, accountable to surrounding governments
Benefit: eventually agrarian and semi-autonomous, semi-isolation from modernity and crowds
Buy up cheap inner city housing and populate local government. Many metal bands started in this setting.
Cost: chronic poverty and almost no agriculture, accountable to surrounding governments, high crime environment
Benefit: eventually semi-autonomous, close proximity to metal culture venues and patrons
Experimental society design ostensibly for academic research for post-carbon society and sociology.
Cost: reliance on startup grants, engineers, scientists, scholars. Accountable to outsider expectations and surrounding government.
Benefit: living off the land, green tech, localized economy, limited modernity and no crowds. Semi-autonomous.
