Bitcoin exists in a system that is supported by the state. Money requires the state. You're thinking in very limited terms. Think broadly: in a society which does not have security guaranteed by the state, there will be no economic systems.
Historically, states and credit-based money came first. THEN came the unit of account and medium of exchange money that you are talking about.
Going back to the original point, can you go to a deserted island and make "money"? No. You need society. You need government. You need an economic system. The money is only partially "yours".
