I think you knew exactly what idea they were saying. Agency, the ability to control your own life, varies. Clearly and obviously a regular person in the West has more agency than say a regular person in North Korea. It is not an one-off switch. The ever growing wealth inequality is making the population shift more and more to the slave side of things. That doesn’t mean that you are a slave it means your papa was less of a slave compared to you.
This is why being a lolitarian makes you stupid. It bifurcates slavery and freedom. It defines force to be a specific term, that no one else uses, and declares victory in the game it is playing with itself
