But if the people decide they want none of it, they can vote for a government that will put people in jail for using crypto in the open. I mean, some voted to leave the European Union, so why not that ?
That would be fun trying to see that happen in a public referendum. Crypto is people-friendly or at least gives the illusion of meritocracy and equality.
Otherwise, people could still trade on off-shore exchanges, and exchange secretly (drugs are still selling on the streets, aren't they?) on the streets.
They'll not rollover. But it'll happen in two ways: 1. They don't understand it (never underestimate the stupidity of politicians and regulators) and thus they'll either allow it or not know how to stop it; or 2. Crypto is widespread and the government has little control over on-off ramps. It doesn't help that crypto-currencies wreak havoc on their economy stability (which further makes them unable to control the population).
