This isn't true. The US is somewhat of an outlier in how liberal the abortion laws are here. What's likely is that, should SCOTUS not bow to the inevitable mob that will come after this leak, blue states keep their liberal abortion laws and red states don't. Most of the country will probably have abortion laws that look pretty similar to those of e.g. Germany.
I don't see an issue; this is Federalism and it's by design.
