The Constitution never granted courts the power to create new laws or rights. It set up a specific formal procedure for amending the Constitution. There is no "right to abortion" in the Constitution. You're the one who doesn't believe in the American form of government, because you don't want the people, through their elected representatives, to decide these issues. You want a bunch of senile unelected judges to do so.
What you won't admit is that the Court interprets the Constitution and gives the people what they want. When the court errs, the legislature corrects.
If the people of the United States didn't want abortion legal, after all these years, the executives and the legislators would all be pro-life, all appointing and confirming pro life judges. And abortion would be illegal.
Even if somehow Roe was overturned, abortion would continue almost everywhere.
