I'm not telling you that at all.....
I'm merely pointing out the lunacy of trying to have governments agents regulate plants or chemicals.
If you grow castor beans and refine them you can make an extremely deadly neurotoxin, just like if you grow poppies and refine them you can make heroin, ephedra-meth and on and on and on.......The "crime" that triggers enforcement may not logically be possession or refinement of plants or chemicals but the inappropriate and harmful use of the compound....
Argue that premise and you might find us closer to agreement....
I think I'm close to agreement with you. I'm not for government preemptively punishing people for doing stuff they haven't yet done yet.
Heroin and meth have uses that, while I would consider them sinful, shouldn't be crimes. Their possession and use aren't always linked to criminal activity (I'd say according to Biblical law but we can even say pro-life libertarianism, which is close enough for my purposes).
On the other hand, even the prototypical anarcho-capitalist Murray Rothbard argued that nuclear weapons should be illegal because they could ONLY be used to commit murder. They were to be banned under Rothbard's logic not because they could be used to commit great harm, but because there is nothing else you could do with them. Even owning a nuclear weapon is a threat against all of your neighbors, and thus a crime.
But that doesn't mean nuclear power plants or uranium should be banned. Yes, these things can be dangerous but they also have acceptable and legitimate uses, so you don't ban them just because they might be used by wicked men to do evil.
So, if something could ONLY be used as an abortificacent, I don't see why its existance should be allowed. Yes, people will still trade it on the black market. That's life. People need to get used to the fact that government isn't going to catch every murderer and that its unacceptable to turn the entire nation into an orwellian nightmare to make sure it does.
But that doesn't mean murder gets legalized. It means that if there are witnesses or other strong evidence it is punished just like any other crime.
Now, if something could be used as an abortificacent but also had a legitimate use, that would be a different matter.
