The OP referred to recent conservative appointments to the court causing the (overblown) problems.
Republicans have had 47 years to do something about Roe and they have not even tried even they they controlled the White House and Congress. About the only thing they could do is propose and push for a constitutional amendment which they have not done. They get more mileage by being anti-abortion than actually stopping abortion.
Abortion was legal under different circumstances in 20 states before Roe.
It was done at the level of government in which the Constitution indicates things like that should be done.
While a Republican Congress could propose such an amendment, there is no way on earth in the political climate we've had for years that it would ever get past being anything but a proposal. The only way Roe will ever be overturned, as it's not going to happen with an amendment, is for a case involving abortion to come to the Court. The Court doesn't go looking for cases to hear. Cases are brought to them and they decide which ones they want to hear.
