Abortion being illegal won’t stop abortions as people will still do it, similar to how people in prohibition still made and drank alcohol despite it being illegal, but the problem is without regulation and the required medical professionals, people will preform it either through sketchy people who claim to be doctors, who could cause injury or death to the patient. Similar to the example with prohibition, people would go to the mob to get it or would make it on their own, and the mob happened to be violent and could kill you if you did something they didn’t like and making your own alcohol could kill you because of the chemicals being toxic or you exploding your self. Making something illegal won’t fix the problem, it will just drive people to seek way more dangerous options
