This is not really correct.

When a stablecoin is issued on a public chain then the issuer cannot secretly censor transactions and the activity of the issuer in general is auditable.

You also get access to all the magical DeFi stuff.

Other than this you, as a person, don't need to be aligned with the current political regime you live in to open a stablecoin "bank account". This on its own is a huge breakthrough.
