That was the same argument used in Alabama after 1967—that the marriages ordered by the Supreme Court were still in fact against the State of Alambama’s law (as well as multiple other states). They fought being told what to do for three years, until United States v. Brittain.
No, these are two separate issues.
In 1967, the feds were actually VALIDLY enforcing the 14A which forbids state segregation laws.
Here, the feds have NO constitutional authority whatsoever to interfere with state marriage laws or to meddle with marriage in any way.
