I see at least two implications of what I said, one being that freedom is an absolute zero, the other being that shifting freedom around is a zero-sum game. Maybe these two are related in some game-theoretic way, I'm not sure. The only fundamentally productive way of obtaining freedom is by getting more control over our environment, i.e., technological progress.

I understand the distinction you're making between freedom and free will; I mentioned it because the compatibilist notion of free will is what you're calling freedom here. But yeah, it's probably not too relevant to the original discussion.
