Everyone finds a way around breaking laws, though. I don't understand what you are trying to prove.
Yes, no law is 100% effective; if it were, we wouldn't need police or courts. My point is that the worth of a law is judged on its
actual effect, not its hypothetical effect if everyone obeyed it perfectly.
If a law can't be properly enforced, it's a bad law. If people can avoid complying with a law just by jumping into another jurisdiction, it's a bad law. Here's another analogy:
A bit over 10 years ago, the City of Toronto tried to make all bars and restaurants non-smoking. It didn't work. It was hard to enforce, so some bar patrons ignored the ban and smoked anyway. Others drove the extra 15 minutes to bars just outside the city limits (this was before the surrounding municipalities were amalgamated into Toronto, so the city was much smaller) and smoked there legally. After a couple of months, the law was repealed because it had no point.
This situation was a lot like what you're suggesting: some abortions will continue in the US illegally (and with much greater harm associated with them, BTW) and others will just move to where they remain legal.
I really don't understand what your definition of ineffective is. It seems that you're saying (though you're probably not), that any law people find a way to break is ineffective and that just doesn't make sense.
My point is that it's set up to fail. In other places where one country prohibits abortion but another nearby country continues to offer them, this is what's happened: women just go out of the country to have their abortions.
Any law has costs associated with it; it may or may not have benefit. The trick is demonstrating that the benefit outweighs the cost.
Here's what prohibiting abortion would do:
- cost: it would create a limitation on freedom.
- benefit (arguably): it would reduce the number of abortions... but only those abortions that don't happen anyhow (i.e. illegal or out-of-country abortions).
- cost: it would increase the number of illegal abortions, which have much greater risk of harm for the woman them than legal ones.
- cost: it would increase the birth rate of unwanted children.
So... if you want to show that prohibiting abortion would be a good thing, what you need to do is demonstrate that the benefits of the prohibitions would outweigh the cost. This likely means you need to do a couple of things:
- quantify the benefit of preventing a single abortion. Just about everyone here, including the pro-choice people, think that there would be some benefit associated with this. The point of contention is how much benefit (which is where the question of whether the fetus is a person usually comes in)
- estimate how many abortions this prohibition would actually prevent (which is where my point comes in: if an abortion just happens somewhere else, you haven't prevented it).
- quantify the value of the other things involved, like freedom and the risk to the life of the woman of a back-alley abortion.
