The United States has already tried the experiment where each state had the right to declare a person a "non-person" and this was a total failure that nearly destroyed our Republic and left scars that still exist to this day.
It took a civil war to resolve that. The courts failed. The legislative body failed. The executive body didn't do anything until secession.
Where are we today? The courts continue to fail us in the fight for Life. It seems every time a good bill concerning Life is passed at a State level a federal court stops it. Is violence the only way to resolve this? I don't think so. Every time a John Brown figure starts killing abortionists we condemn them and after they are caught convict them.
So how do we win this battle? I think the State sovereignty approach might work. The vast majority of States will ban abortions with very limited exceptions. Our resources then can be focused on the few very liberal States. As it stands now we are fighting for a Life Amendment that we can't even get voted on in the Congress.
The problem with the fed govt dictating to all is self evident in the obama presidency. It's great with a good leader, but all it takes is one evil person to radically transform this country. Under the obama regime we now have the fed govt using our tax dollars to subsidize abortions.
