I'm a bit confused by the figurative language used here. Did you have a specific example of this, or is this a hypothetical? I think this type of thinking has its, but I think it's important to contextualize it. For example, you can say that a gambling addict gambles against their will, but I wouldn't say that they are enslaved to gambling institutions (unless I was purposely being hyperbolic). But I agree that many systems of slavery had a degree of self-regulation among the enslaved.

My framework is this: violence is a necessary part of slavery, because to a certain extent enslavement requires the enslaved to choose between continued slavery or extreme violence/death. If you remove state violence from the equation, slavery still usually exists, and often flourishes due to the lack of a countervailing force. In "top-down" situations, where a system of slavery has implicit or explicit state support, the state doesn't have to explicitly enact the violence itself, it can simply declare a certain segment of the population "extra-judicial.
I think authoritarian, low violence states like Singapore have numerous human rights issues, but I wouldn't go so far as saying that the entire body politic is enslaved.
