A true Nomadic society actually needs to have modular, easy-to-move around, mobile buildings. The buildings would need to be light, easy to build, carry around and assemble.
I think Nomads living in uncertain times need alots of Bitcoin-type decentralization in most aspect of their lives. Don't think I would trust monarchy unless it's led by saints.
Will hopefully go through the youtube videos soon.
If that is the criteria for Nomadic then I think that living on luxury cruise ships is going to be an example. Or living in a trailer truck and always driving in highways. Nomad doesn't really need it but bitcoin can help them ease their nomad life but considering that most places do not have a bitcoin ATM or any businesses that accepts bitcoin as payment as of yet, I think that nomads will have to stick with cash and credit cards.
