I don't know why people continuously fail to realize that moral disagreements have no legal solutions.
Fortunately,
moral disagreements require no legal resolution. A politician's
morality may not be constitutionally imposed by state instruments on
other citizens.
....so naive.
Only a politicians morality (or corruption) can be imposed, only the citizens morality (or corruption) can be imposed. There is not a single law now or ever that does derive its claimed authority from a moral premise nor is any law by definition anything less than a matter of violence.
If you look at the world around you and wonder why no political disagreements are ever solved it's because people believe in inexplicable myths like amoral law.
You say "may not constitutionally" yea where in the US constitution (and that was the immediate context) is that? It's not there, nor is privacy, nor is a guarantee of abortion, nor a strong guarantee of liberty.
Why would an abortion ban be a problem? If the answer isn't moral it's irrelevant.
Why would a political right to abortion be a problem? If the answer isn't moral it's irrelevant.
"Why does the moon circle the earth?" That's an amoral question. "Why should I go to the moon?" Is not, anything with "should/ought" will root itself in values or it is mere assertion. The word "problem" rests upon a foundational context of an intention or an ideal that is prevented. There are no problems without goals and no goals without values.
You said "is necessary and appropriate." about a constitutional amendment. Necessary for what? Appropriate for what ideal outcome? Because people want it? Why do they want it? Why should their wants matter?
On top of that "privacy" is a good thing, but no one who views a certain behavior as deserving criminal punishment is going to consider that behavior a matter of privacy. You can guarantee privacy till the cows come home and somebody is going to come up and say "patriot act, terrorism isn't a private matter", "killing babies isn't a private matter", "sodomy isn't a private matter".
Privacy, as a value, only makes any sense as an implication of liberty... and not a vague liberty something precise which can be consistently applied by all observers to any situation.
