Someone argued that private prisons have an incentive to enslave people and that it would be bad for there to be private prisons under anarcho-capitalism
Others have argued that private prisons would be rarer and crime might be more in fines or other ways of making restitution rather than prison times
What problems exist with the idea of private prisons and what solutions do you suggest to these objections?
Under an ideal AnCap paradigm you can't enslave someone against their will. People only go to a prison of their choice as part of an agreement to fulfil a contract as a condition to be allowed back into polite society. (living in some territory, or doing business with certain groups, whoever have come up with such a pact)
Of course we can argue whether that's realistic, and what would constitute unlawful imprisonment under the NAP vs. what would be enforceable, but no government is perfect. (I say government because IMO AnCap is still a loosely governed form of state without the trappings of a state.)
Since most people don't like prison, you're correct that fines and other restitution would be more common.
We really don't know how well private prisons would or wouldn't work, because we don't have any fully private prisons. They are all incentivized or regulated by the state. Maybe there are some historical examples.
Most of the future models I've seen, someone who did a serious crime would essentially be declared an outlaw and excluded for whatever allied turf the victims lived in. They(their families, tribe, insurer) would have to either pay the "blood price" as compensation to regain access to be in that region, or face summary execution by whatever people/machinery were doing security.
I think BadQuaker.com had some podcasts going into restorative justice and all that vs the modern nation state system of warehousing people until they turned 35-40+ and the testosterone settled down and their brain cells started working again. Although, when you warehouse someone with a bunch of cons for a number of years, or even months, a lot of stupid anti-social behaviors get pretty well cemented in.
The restorative justice systems, which are growing fewer and fewer, but still have some presence in different Muslim controlled regions, tend to do more to address victims compensation. This keeps the family/tribe of the victims from wanting to hunt them down and kill them, in theory.
In a more established nation/state where you have pretty much all people in relation to a real or imagined state entity, all crimes are against the state, the state mediates all justice, all fines are paid to the state, the welfare of the general public, and victims derives from the state, so any meager compensation(usually nothing) would come from them.
Which ends up being abused, because the state entity doesn't really care about the welfare of the people. 3-4 people get murdered, ok, lock the guy up 10 years, let him out on parole down the road, and see if he can go back to being at least a low level production worker. The victims family, oh well, they can apply for welfare, cash in their insurance, whatever.
A vandal sets fire to an entire parking ramp full of cars, in a restorative justice system that little shit would be mining heavy metals in some slave pit until the day he died if his family/tribe couldn't compensate the victims.

Most of the old podcasts on this stuff that I remember have faded from the internet along with their creators. Oh well, so it goes.
