No judge has the power to abolish it by fiat. Article VI forbids it.

Yes!!
Procedures for amending the Constitution are clearly prescribed in the document itself. Justices and judges deciding by fiat isn’t one of the options, as you say.
Once SCOTUS vacancy is filled by POTUS, even the fiat option is inoperative.

I swear. This winning. Most fun election of my lifetime.
