No one should assert that SCOTUS decisions are always right or always wrong. However, unless overturned by subsequent rulings on the subject, or no longer valid due to specific changes in the law, they hold the force of legal interpretation which must be followed in all lower courts in the USA.
The terms "right" and "wrong" are often relative to the ideals and beliefs of the Society one lives in. Such ideals and beliefs can change over time, and thus so too the laws can be modified or changed. Hence your list of examples.
Even using your examples, when related to abortion "society" remains divided in the USA on the issue, not just the act, but when and if it can be conducted.
We have people who argue it must be an absolute right, and at the sole discretion of the woman carrying the developing life or lives (twins, triplets, etc.) within her at any point up to and including immediately after birth. That NO ONE, not the father, the family, the physicians, nor Lawmakers/Judges should have any say whatsoever.
IMO this is a ridiculous assertion of absolute rights. It ignores all the "rights" both human and legal we grant to any citizen of this nation, and often to visitors legal or illegal. It ignores the fact that we ALL exist via this process, including every woman who survived their birth. It also ignores all the methods available to prevent this from occurring, from products to inhibit insemination (condoms/diaphragms, IUD's, birth control pills), to morning after pills and so on. Not to mention simple abstinence.
Basically, especially in the latter period of this process, we are not dealing with a "thing," we are dealing with what every one of us was at some point during the nine or so months leading to birth and our continuing lives thereafter.
My argument is not to deny choice, but to point out that this is not like some "accident," it occurs because of choices made that allowed it, when it could have easily been prevented by choices before it became an issue of another human life.
