I kind of see it as the ability to act as we desire, but not having the ability to desire what we desire. That definitely just circles back around to not being in control of our actions, but the main takeaway I took was the counterargument that we must come from somewhere as our definition of who we are is the sum of our experiences, environment, genetics, etc. If you take all that away then you are not really you anymore so you should kind of just, accept that I guess? Maybe you are right about the emotional aspect of it as this argument seems to hint that we should take some pride in our past. Kind of like, well we can't really have changed who we are up to now but the alternative is nothingness so let's try to make the most out of it.

Perhaps this is the natural conclusion even if deterministic that we are designed to come to? Giving people the illusion of free will helps encourage them to survive and make the most out of their life?
