Bitcoin is essentially a large public decentralized ledger that says someone over here has an entry of a certain number of units and can move them to another person over here.

All that transferring Bitcoin is doing is entering a ledger entry which says this unit was transferred from here to here, one address to another. It is a statement of truth, expressed with math.

So essentially when politicians seek to use force and threats to regulate Bitcoin what they are saying is that they object to a true statement being publicly and transparently expressed through math.
