Think of all the sin we could avoid, how much easier life would be, if only we were not made human. There's gotta be something wrong with that reasoning.
It sounds like hell: an existence utterly devoid of pleasure, work, accomplishment, progress and change. Bleah. Count me out.
I believe the Preacher dealt with a lot of this stuff in his writings; he called it "meaningless, utterly meaningless" and concluded in the end that it was right to serve God regardless.
Thirst makes us appreciate water; the joy we get from scratching an itch is proportional to the aggravation of the reach; the simple pleasure of eating is enhanced by the gravy of hunger ... all these things in their dual opposites are gifts of God.
The difference between this and the crack addiction is that crack destroys you; hunger and thirst, kept in balance, do not destroy us but instead increase our little joys when those needs are satisfied. No one wealthy appreciates his wealth like the one who knew poverty first.
In the case of food, drink, sexual pleasure, rest, and so on, you can see a reminder that we are not self-sufficient and all-contained, but need others and their gifts in order to keep going. And that steady humbling should keep us mindful of the source of all good things.
