I'm sure you know that's beside the point. Free labor isn't that free when the only alternative to trading the most useful half of your life to corporations is starvation in the streets. And the only alternative to that is dependence on a state's social safety net. Neither may be outright chattel slavery or literal feudalism but in modern society where people truly own so little, even of themselves, it isn't freedom either.
Oh, it's exactly the point. You've conflated freedom with being free from want. Freedom means being free of other people forcing you to do things. You can go about satisfying your wants any way you want to, as long as you don't force others.
That's what free labor is.
If you believe you're entitled to the fruits of the labor of others, then you've enslaved them, and that's not the moral high ground.
