Hey,
Interesting topic...though not sure if i get it fully. I think what you are trying to say is that there are two levels of freedom, biological, and well, societal. We can manipulate the biological aspect of life, obviously, although sometimes i wish it could be a bit better. And then there is free will in general, apart from the biological aspect of it all. From what i get, you don't believe in free will, but rather, a combination of events that created the reality that you live in now.
I'm not gonna pretend, i am no philosophist, but i do like to think. I think we have more freedom then we give on...although a lot of it is steered by environmental factors. You could try to take them out of the equation, but then what would that leave you with?
personally, i think people are just too comfortable with societal norms. It allows the majority (key) of us to live comfortably. It is only when you become the minority that gets screwed, that you start questioning things. Does it all make sense? No. Whatever, you probably already know this.
In terms of free will...I think most of our choices are regulated by our own inhibitions and fear. We are only limited by our fear, and by certain societal norms that govern our world.
Take away societal norms, and what do you have? Chaos? What governs those norms, anyways? Survival of the species, a gut feeling what wrong or right is? does that mean we are inherently good, if we create these laws out of nothing? Or is it transcribed in our genes?
I dunno, i think life is fundamentally good, with societal bullshit skewing our perception. I also think we do have free will. That comes with being concious. Just to question if we have free will or not, doesn't that mean we have the choice?
ps. this is a lot of random thoughts. I have so much stuff going through my head, hard to focus it
