Two problems. First: Doesn't logically follow that people cannot choose something for no reward whatsoever. You can do this experiment for yourself.
Second problem: Rewarding does not necessarily mean "feels good."
We set our goals as rewards.
Not necessarily. Goals can just be goals.
Our desires are based on what feels good.>/i>
Desire≠values.
They can but not on their own will.
Rewarding does not necessarily mean "feels good."
I can't think of something experienced as a reward that feels bad. It wouldn't be a reward.
Goals can just be goals.
Are your goals to fail, be fired, starve, go broke, get sick, be killed, or hurt?
Goals of NORMAL people are to achieve that which feels good, your goals notwithstanding.
Desire≠values
That's novel. We desire that which we value; nevertheless, base don your arguments you may desire worthless, dead-end things.
