We have dozens of laws on the books that are as hard, if not harder, to enforce than an abortion ban would be. There are other first world countries with such bans.
Name one.
South Korea, Japan, Chile, Finland, United Kingdom, Poland and Parts of Australia
IThat is a broad definition of "illegal". In almost all those examples, its an administrative issue, not a criminal one. "Pro-Voice" than pro life or choice. I think in Poland you have to prove a particular dire need and there are no abortions in Chile (I heard almost every girl in jail is on jail for that there), but in the rest you just have to prove a substantial or demonstrable need to a second doctor or hospital that you need one. I think that would be a good post-Roe compromise.
I mean a law. Name one law that causes more problems.
Rape is probably a good example these days, as are the drinking age and drug prohibition. Simple things like tax evasion of purchases on the internet are almost certainly harder to enforce as well. I fail to see why abortion laws are supposedly uniquely unenforceable.
