You may have lost bitcoins, but you did so before you knew they'd be worth hundreds of dollars. I'd expect that in the future, people will be much more careful to backup (or print out) their private keys.

In any case, the ones you lost just increased the value of all the other bitcoins still in use. Since each unit is theoretically divisible into infinitely smaller units at some point in the future, people will just trade smaller amounts for larger values. That's a feature, not a bug!

A lot of people are claiming that deflation is a death sentence for a currency like this. Something they overlook is that new coins will continue to be created for many years still, and that all it takes is a new version of the protocol to 'fix' any fatal flaws in the current system. If the majority of users have a financial interest in defending the value of their coins, it seems logical to me that they are likely to act rationally to achieve that if a threat were to emerge.

But then, who knows.
