Oh, this again...
Hedonism gets you into trouble.
Buy creature comforts, you lose money.
Eat tasty food, you get fat.
Interact with others, you get taken advantage of.
Smoke cigarettes, you get cancer.
Curse out your boss, you get fired.
Go on a killing spree, you get the needle (in most states).
And with that last one, you are likely to make a big mark in history -- everyone remembers the killer, no one remembers the victim.
As for happiness, money is the only stable way of finding happiness, because knowing you have it makes you feel secure.
