I’m glad you brought this up, because yeah we’re all selling our bodies and time. I wouldn’t say this means we consent, though. We don’t need to change what consent means to make capitalism sound better than it is.
If you’re “incentivized” (e.g will be starved and punished otherwise) by a system to do something you hate, you can’t call that consent.
If you had a system where women were raised and then presented with the option of either having sex with you & being allowed to participate in modern society, or being discarded in the wilderness, not being allowed to even build anywhere/make it on your own because all the land is owned by either private individuals or the government, then those women aren’t free.
As we agree, just by changing the demand from “have sex” to “do manual labor” or “rent out your mind so someone else can own the product of your thoughts (IP)” doesn’t change whether or not it’s consensual.
