One thing that is enforced legally is the IOU. It used to be that a note meant that the bank/government owes you gold for it. Since USD is now fiat, the IOU is in the form of ensuring that your debtors actually pay you (simplest form is loans or bonds). Within a jurisdiction that would be done in different ways with the court. Between countries it would be done with the military.
On ethereum, the IOU is that you’re granted a vote to shape the code of the network, and also you can are owed some structured computation cycles.
