No. This just underscored that if you don't encrypt stuff them idiots will break it. Notice that they didn't break any parts of TLS 1.2 which were encrypted, everything they broke is the unencrypted stuff, and so by encrypting more stuff (everything except client hello) in TLS 1.3 we improved that, and then by encrypting even more stuff in ECH (Encrypted Client Hello) we expect to improve it again.

Government regulation is good in that it can work, but it's terrible in that almost every other choice would be better if it works. For TLS 1.3 we made choices which work, if we'd waited for your hypothetical government intervention we'd still be using TLS 1.2 and Trump would presumably be collecting an inaugural "Super good Bank Encryption Champion" trophy from EDCO or somebody who fought against TLS 1.3 because it meant they'd have to actually do a good job.
