The most popular stablecoins aren't trustless, proving the parent's point.

Parent's point is weak - it's not possible right now for people around the world to hold fiat/stocks in their own centralized, custodial wallets due to stringent KYC/AML, and blockchains currently fill that need for stablecoins, and will fill that need for tokenized stocks, treasuries, etc.

And again, nobody needs blockchains to tokenize centrally issued securities.
