If you understand how the US Government works, then you understand that the Supreme Court cannot establish ANYTHING by removing laws. (ie overturning previous decisions).
What the Supreme court did was allow for the POSSIBILITY of a fully Catholic US State to practice Catholic religion with respect to abortion. It ALSO allows a fully Jewish state to practice Jewish religion however they want with respect to abortion.
They actual problem caused by overturning Roe v Wade is that some states who's laws are already catholic will regain the power to stop abortions in their state. That's it. California, New York, etc, are absolutely and completely unaffected by this decision, for example.
