Rather than interpreting her stance as supporting this, which is probably wrong, there is a much better stance to take. RBG herself said that RvW was an unusual decision, that broke the SCOTUS tradition of siding with established jurisprudence and making minor corrections to the conduct of law.

She herself said that RvW swept away an entire country of existing laws, and that this was something the SCOTUS did not usually do. She stopped just short of saying it shouldn't do so, but she clearly felt that way.

She was not an uncomplicated supporter of abortion, and that even RBG had problems with RvW, exposes it for the freakish decisions it was.
