Exactly. At least, the heavy regulation or ban of stablecoins is just a proposal by central banks worldwide. The final decision will lie in governments themselves. So far, it's been nothing but "talks" without concrete actions whatsoever. I believe that no one cares, since the crypto economy is still smaller than the global mainstream economy. Rest assured, that once crypto becomes a serious threat to the existence of Fiat, governments will do anything to try to stop it. While they may succeed in cracking down on exchanges, they'll never be able to prevent people from using crypto as an alternative to the existing monetary system.
Centralized stablecoins might see their demise in the long run if they're unable to comply with regulations from governments worldwide. But decentralized stablecoins will live longer because they're entirely governed by the Blockchain. Centralized stablecoin issuers are the ones that need to be worried as they could face fines from the government. The average person can simply switch to another centralized or even decentralized stablecoin if one of them fails. While the demise of centralized stablecoins could affect the crypto market in the short term, decentralized ones might take the lead in recovering the same at its fullest. Just my thoughts
