The Legislature and Executive can pass a new law that overrides a decision that ruled on existing law.
This is pretty directly refuted by Dobbs. Roe v. Wade was not ambiguous and was a settled matter of constitutional law until the new court decided they didn't like it.
I don’t like the decision here as well for political reasons, but if you read the arguments the Supreme Court is just saying that abortion law is a state issue not a federal one. Which limits the power of the federal government. Which is good.
Looking at how Southern states seem to be competing to out-fascist each other right now, devolving everything to states' rights seems like a bad idea. If it were entirely left up to the states, half of them would be hunting gays for sport. Having common standards as a culture enshrined in law and a central government strong enough to protect and enforce those standards also seems good. It's weird that this isn't even up for debate where gun rights are concerned but bodily autonomy, rights to privacy and free speech are all up in the air.
I don't like the results of the Dobbs decision either. But the root cause of the problem was always legislative, not judicial. When the legislature fails to make the laws clear, anything that ends up in front of the Supreme Court is going to be a toss-up. Tell your members of Congress to do better.
For all it's faults, I would argue the Supreme Court has worked reasonably well - because the justices do not seek elections and do not owe loyalty to their appointees. And anything they do could be relatively easily undone if the US could ever be bother to pass laws again.
In a way, you can almost think of their decisions as open-source. All of their arguments are written down and you can actually read their reasoning for yourself (as opposed to some of the dire interpretations offered by journalists). There are some notable exceptions (Alito and Thomas), but for the most part you can read their arguments for yourself and see that most of them are pretty professional and fair-minded.
> I think it is quite optimistic, if not even downright naive to assume the text matters at all for such protagonists.
If anything, the newest court is doing the opposite of what you are worried about. They are willing to throw out established precedence where there is not written law. In a way, the new court is leaning more democractic to a fault.
