I have used the cream in coffee argument before. There is nothing in the strict reading that says the right exists as neither cream nor coffee are mentioned.
The bill of rights have become a problem, too many believe we only have those rights. Some at the time feared that would happen. As you note, it is incumbent on the government to show cause. I may disagree with Dobbs but I have no doubt case can be shown abortion is not a right. Just because I do not believe a fetus, especially pre-viability, is not necessarily guaranteed rights does not mean I do not get why someone like Crazy believes the opposite.
But as you note, Alito strikes down Row for every conceivable reason. He did not stop at the fetus argument. So while he claims it does not apply to anything else, one wonders why he bothered with the rest of the argument as all the rest most certainly can be applied.
