I'm not sure if I understand your question. Are you scared that the gov will see transactions, or are you scared they will infiltrate it to sabatoge its intrinsic value?
The currencies have different potentials. If they want to regulate one coin to work a certain way they can do that. They won't let people demonstrate as a coin community if thats what your asking because in specific countries the rule of fiat liabilities arise. Can they protect the digitial peer to peer technology, yes. Will they let people guise its use for utility uprisings, no. I know if they need it, they will find a way. We know the limits within reason for a global thing to work. These niche coins, are meant for borders. To each border its own. But few coins will have rules we don't misuse in specific regions.
