Not giving Federal taxpayer money to PP doesn't stop them from doing abortions (they officially claim they use no taxpayer funds for abortion anyway), and you can't ban abortion via statute due to Roe v Wade having supremacy. (BTW, PP does a minority of abortions in the USA.)

Even if the USSC wanted to replace Roe v Wade, they can't just do that by decree. A relevant case that would give them that nexus would have to navigate itself all the way up the chain from Federal court through the corresponding Court of Appeals (assuming they even hear the case), winning all the way in courts laden with Obama appointees, to even get on the USSC's radar.

You didn't understand what you claim to have read.
