Or to put it another way.
Say Bill gates comes to you and says.... "I bet you a billion dollars that if you pull out a coin and flip it 50 times, It will land heads everytime."
Would you do it? I would.
Now I'm assuming your not a billionaire here... so you obviously can't cover it if it DOES land heads everytime... but the likelyhood of that happening is soooo remote... you pretty much have to take that risk.
Heck it's even better in the derivitives case, because it's not bill gates giving you a billion dollars... it's a billion dollars of wealth being added to the world... which improves everyones lives through investments, jobs and economic growth that wouldn't happen before hand.
You've just got to be careful of someone slipping in a two-headed coin and disrupting the natural order of things.
