CO is the LAST PLACE ON EARTH I would want to move...for various and sundry reasons.  Look at what the state government has recently passed if you don't already know.

A town of 200 isn't going to cut it, period.  It's going to be far larger than that and 600 acres isn't a dent in what you are going to need.  You're going to need 5-6000 MOTIVATED people to give the finger to the US/State government and pull a Galt's Gulch (read Atlas Shrugged) to pull this off, minimum and doing it all via bitcoin isn't going to work unless they were ALL early adopters or were independently wealthy to start with.

Sorry, again, not a troll but trying to give you an idea of what REALLY needs to be done to make this happen.  Even the earth architecture takes non-recyclables that cost a LOT of...something to get going.
