If you generalize from drugs example, crypto (may) help you do things governments do not want you to do. Drugs are just one widespread restriction; and you may view Western governments as generally competent and benevolent (to be clear, I do not), and drug prohibition as necessary evil.
But it's hard to claim that most governments around the world and competent and benevolent, and easy to get excited about people being able to bypass things from capital controls and ruinous inflation, to outright censorship and confiscations. Not that I think crypto would actually succeed, but I hope it does.
