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.
I would love to agree with this argument. And maybe 5 years ago I would have. But so far crypto has not demonstrated that it can really solve the issues you are listing. Yes, it can result in some capital outflow from oppressive countries, but that does not have a big impact on these people or the regimes. The stories that are being written are not of a hard-working farmer who was able to save some monero and move it to a different country anonymously. Instead, we are seeing millions of people lose their savings and/or investments. I acknowledge that things might change in the future. But as of now I am not optimistic.
The main difference here precisely "not your keys not your coins". Replacing govt-influenced/controlled banks with some rando pseudo-bank is only a net positive for a really terrible govt...
And because of the complexity, I doubt crypto will succeed in its goal. It might get regulated but then it's probably no better than banks, since it would be restricted from the uses a govt doesn't like similarly to money in a bank.
