Except that you have universal agreement that murder is wrong. Police will arrest, prosecutors will prosecute, juries will convict.
You don't have that with abortion laws. Even before Roe, they were rarely prosecuted. (And often only because the abortionist screwed up and maimed the patient.)
I've said, put me on an abortion jury, I'll vote to acquit, I don't care if you have video of the provider throwing Globby the Fetus across the room and yelling "Three points" when he hits the medical waste container.
Nope, it's a fine reference. The constitution is a fine document despite its MANY flaws, but it shouldn't be a substitute for common fucking sense.
