AFAIK, all the laws tossed by SCOTUS, regarding abortion, have been state laws. That's the major point of the dissents in Roe, Planned Parenthood v. Casey, etc. That a court is taking on a legislative function, on an issue that is contentious to the public. Once judicially determined, the public debate is inflamed with no place left to settle it, short of Constitutional amendment.
You may be right.
Many have argued that Congress cowardly allows the Courts to do things it does not have the guts to do.
