This is availability heuristic. Many financial innovations work out well and power everything we do today without a second thought. Credit cards, internet banking, mobile banking, etc etc etc. Should we ban all financial innovations because a subset can cause collapse?
For stablecoins, the difference here is that all data is open. So for example with the latest news with MIM/abracadabra, all the loans/treasuries and collateralization ratios are viewable by everyone [1] and on chain as well. For Dai/frax/etc as well.

For ICOs, this exists today as well in our regular regulated markets as well. Don't tell me you think AMC or GME is worth what they are worth.
> Crypto hasn't created anything new fundamentally, it's just re-hashing all the stuff we outlawed before because it was an objective breeding ground of fraud and crime and grift. The only thing new about the crypto economy is that the pitches are structured as "${previously_failed_idea} except on the Internet."
I'm not sure this is true.
