You can’t force people to be responsible.
You have about 330 million people in the United States and hooking up and casual sex will always be a thing.
Those women and men are still going to have unprotected sex and women are occasionally going to get pregnant a lot if these women are going to forced to live with the consequences while others will go to more liberal states and Canada to have a procedure.
I fully expect a lot of doctors and other individuals with a healthcare background to start doing abortions underground and off the books now even though it’s deemed illegal in some conservative leaning states.
That'd be stupid and wreckless on their part and a lawsuit waiting to happen. It wouldn't even be worth the risk of losing everything you've ever worked for to help out someone that you don't know.
