McDonald vs Chicago already incorporated the 2nd amendment (as interpreted under DC vs Heller) against the states. This has not been the case for abortion or limited privacy rights recognized under Roe. There's no novel argument in this article.
The how and on what grounds is that really matters in the Supreme Court decisions.
SCOTUS could have used other ways to effectively ban on abortion, but they are power tripping and drive straight off the cliff.
I think there is 50% change the US is illiberal-democracy like Hungary within 10 years.
