The issue here though is that abortion isn't in the constitution. It was effectively created by the courts out of whole cloth with the Roe v Wade decision, and not even in the "right to medical privacy" sense that a lot of proponents paint it as. The ruling itself was as narrow as possible to only apply to women seeking an abortion.

It's 100% made up.

The solution to something that is made up is to target that, not to undermine all other rights by crafting a 'solution' that could potentially be used to undermine any other right.
