There's no way someone in an AnCap society could be prevented from vat-growing slaves by the dozens, or doing what he wanted with them unless your AnCap society has enforcement mechanisms (aside from lynch mobs) to prevent that sort of thing.
Probably true, despite Sandy's theory that we can have complete freedom and still not let anybody get away with anything that the twenty first centurian might disapprove of, but the question presupposes that those good bureaucrats will be better than mere mortals.
Observing state interference in families, the interference is generally harmful rather than beneficial to children, so on the whole, chance's are the technology is likely to be used less for evil purposes the less it is a state monopoly.
All the problems that could happen with cloning are rather similar to the problems that already happen with conventional reproduction.
Disagreeing with both you and Sandy: How come an anarcho capitalist society will supposedly both allow abortion and forbid infanticide?
Will anarcho capitalist societies enforce the marital contract or not? And if they are going to enforce it, it is going to be enforced largely through families, hence marital contracts to the extent that they exist, will necessarily be patriarchal.
Let us consider US reproductive law at present: Abortion is a woman's right to choose, but child support is not a man's right to choose. If you have drunken sex with some anonymous woman in your car behind a club, she can stick you for the pregnancy if she has enough information to trace you - and if she does not have enough information to trace you, she can stick it to her husband even though she has refused to have sex with him for over a year.
Is that going to happen in an anarcho capitalist society - and if you can enforce that on men, what can be enforced on women?
Sandy seems to think that all politically correct rules that currently apply, will continue to apply in anarcho capitalist society - that no one is going to be allowed to do anything currently deemed bad by the politically correct. such as get women pregnant and then tell them to get lost, while everyone will be allowed to do stuff that is currently deemed OK, such as abortion without the consent of the husband, female infidelity, and female serial monogamy.
I also notice that no one in "Escape from Terra" uses potentially dangerous recreational drugs. Come on Sandy. Surely in the belt Coca Cola really will be the real thing?
So, in answer to ContraryGuy's questions, you probably could get away with creating clones for bad purposes, but clones are expensive, therefore valuable, therefore not lightly mistreated. Further, they have minds of their own, so would not necessarily comply with mistreatment. So producing them for the purpose of mistreatment might be a costly failure.
On the other hand, producing them for sexual purposes would probably work fine, since women are naturally inclined to the purpose - and with the appropriate hormone treatment and upbringing would be even more inclined to the purpose.
And, as for evil things people might do under anarchy, consider that the state now favors diagnosing male children as transexual before puberty, chemically preventing puberty from hitting, and "sexually re-assigning" them - which is to say castrating them.
I notice that female to male transexuals who take testosterone tend to turn rightwards. I bet the state will not be nearly as enthusiastic about handing out testosterone to young females as it is enthusiastic about cutting off the balls of small boys.
