I agree that get rich quick schemes are sad, but on the other hand, when I turn off my adblock, 99% of ads I get on YouTube are for copytrading with traditional stocks on eToro. Financially illiterate people get given a rope to hang themselves with crypto, but it doesn't take away from the benefits of crypto, which I think has a (small) place in any portfolio, and could potentially be a lifesaver in any cashless+NIRP society. I wouldn't try to pilot a plane without training, and wouldn't buy any crypto without knowing deeply about it. I don't see it as a red flag of the technology that people do stupid things, just a sign of human laziness (surely, getting the proper knowledge before piloting a plane, trading stocks, or buying crypto is common sense).

There are many people who want governments to "step in" and protect people from themselves, but governments will likely have ulterior motives (KYC, AML, financial control) when they do so.
