Crypto directly undermines the concept of national currencies (the real US product is the dollar, right?). Crypto would enable people to literally 'vote with their wallet' by exiting from a currency they don't like into another. National currencies are defended with weapons, so until someone uses crypto to buy nuclear weapons, governments will forever undermine and neutralize crypto.
You are immediately going from 0 to 100. A new currency begins with marginal uses and then expands. Give it some time before bitcoin buys nuclear weapons!
That's actually the opposite of how real world currencies work. They do not start with marginal cases and expand. In almost all cases they start with the most important cases -- the government says "you must pay taxes in currency X or suffer consequences".
This is pretty well established in the history of currencies.
