No they wouldn't. They didn't say anything about this being only a states rights thing, otherwise they would say things like the civil rights laws that were passed in the 60s were unconstitutional, and they have said nothing of that nature (yet).

Ruling that the constitution does not grant the right to abortion is also saying that legislating abortion is not an enumerated power. That means that any federal law that bans/bans banning abortion would be unconstitutional unless you come up with a commerce clause reason. Hard to see that flying with this court, so it seems to be up to the states now.

Are you aware Mississippi has a ban at 15 weeks?

That is three weeks longer than France, Denmark, and Germany among others in Europe. In Germany you have mandatory counseling the tries to talk you out of it first.

I encourage you to read the concurring opinions. One justice concurs to explicitly point out that this decision does not make abortion illegal, but merely returns it to the legislative process.

He means the state level legislative process.

Yes, exactly my point

No, it's the opposite of your point.

Tossing a federal law “codifying” a federal right to abortion would not make abortion illegal
