I agree that Congress or the consensus mechanisms of the states are more accurate authorities.
I also agree that it is wildly disruptive to do this. But for that I empathize, and hope to inspire on other ways of consensus making.
The Supreme Court has acted as a second Congress for a wide variety of things. This is how miranda rights happened. This is how contraception was legalized. This is how homosexuality was legalized. This is how race integration was legalized. ETC.
(As just one, like interstate commerce, will keep it on the chopping block by the same court)
also, currently people need to be challenging laws and the court has to accept those challenges, if there isn’t political will to still challenge those things then the cases will never happen
Opposing sides of that court have said the exact same thing about Roe v Wade. Ruth Bader Ginsberg even said "this is pretty weak, going to need Congress here", no different than Justice Alito on the opposite side.
I think your perspective is very common, I think it is disingenuous for different people that should know better to promote that perspective. There is so much the elected representatives and the people can do. This crisis of confidence perspective relies on nobody actually reading these cases.
