Even Congress cannot make a law that violates the Constitution...and the regs on “ghost guns” does, in fact, violate the 2A.
There were literally no serial numbers required on any long guns sold to the public by FFLs until 1968 (with the unconstitutional GCA), or until 1934 on handguns and full autos (with the equally unconstitutional NFA).
Individuals making their own firearms (which has been done since the 1700s, at least, in this country) have never been required to put a serial number on their firearms. There is no authority, that’s why it was never done before.
