There's a West Wing episode (
@Marvin the Martian) where Barlet is interviewing a SCOTUS candidate specifically regarding the right to privacy, and asks him if he'd object to a law that outlawed the use of cream in coffee. The candidate says that he'd object very much, since he likes coffee in his cream, but he would not be able to overturn the law, since there is no constitutional right to use cream.
Now, this thinking is not exactly correct. Even when things are not protected by the constitution, the government is still required to at least show
some reason for passing a law. Laws can't be
entirely arbitrary. But the thinking of this fictional character is very similar to what you see from Alito, and also Thomas.
The problem with Alito's opinion is that he follows the great tradition of so many jurists before him of rejecting an argument on every ground possible. He could have just said, "
Roe was wrong, because one of the interests is that of a potential life, and this interest is so strong that it overcomes other competing interests." But he didn't. He said that, but then he also said, "Plus,
Roe was wrong because there's no traditional right to abortion." And so on. Every concievable defense of
Roe, he rejected. In short, Alito put forward a legal theory of the right to privacy that doesn't only justify the banning of abortion; it also justifies the banning of cream in coffee.
