"Your labour and skills are not owed because they got lucky, they are owed because that is what you are exchanging with the owner to pay back your debt and earn your freedom"
You can use that logic to justify any oppression as long as you frame it in the language of property. It's not a valid argument - you don't have a choice but to exchange for money because you're in a position where you have no choice but to engage in oppressive social structures or face the violence of the state if you want to survive.
It's not a choice. You have a (metaphorical) pistol to your head to engage with the system as it is, die, or be killed.
Its really not so different from what your ancestors as serf or as debt slaves in antiquity might have lived.
As long as you live in a society where private property in absentia (ultimately based on theft, might I add) exists, the "choice" to exchange is colored by violence and is far from truly free.
