Making a nomad base function sustainably seems to involve several things.
The people that come - through various networks, mostly nomads arrive, but sometimes "mainstream" people find us, people who don't immediately fit in. The cool thing is that once they arrive, they either don't cut it and leave, in a natural way, or they learn. They grow, they participate, they become nomads. At least in philosophy.
Necessary for this is long-term "hosts." These are the people that already know how the nomad base operates, and continuously provide an example for new arrivals. A sustainable cycle is then set in place.
