Like feudalism, the lords of the manors have to make sure the peasants stay bound to the lords’ lands.
The peasants are indentured by contrived debts and forbidden to acquire their own land or even trade with silver or gold IF they have any.
Bitcoin, like gold or silver, breaks the chains and busts the gate wide open....therefore it must be banned.
That’s why it’s called “Real Estate” (Royal or the King’s Land) I suppose.
