Re: Bitcoins destroyed if unused, to keep bitcoin supply known?

And remember, eventually ALL bitcoins will be lost!

I don't understand this comment.

Eventually maybe in a thousand years. What he means is bitcoins get locked in certain scenarios. Here is an example or two:
1) Someone mistakenly sends his bitcoins to an unused address.
2) You forget your wallet password.
3) You lose your wallet.dat file.

and the list goes on..

The curve will approach a value well off of the 'ALL' line, and approach it in an asymptotic manner.

The eco-system will weed out people who should not be screwing with BTC through a process of 'survival of the fittest'. I'm cool with that. It was part of what appealed to me when I entered into it.

The more focus put on trying to hand-hold those who are not up to the task of owning BTC, the less is available for hardening the solution against attack. Not only that but there is a correlation between the caliber of people who will throw their BTC out with an unwanted HDD and those who will throw them away using some on-line dice game or send them to TradeFortress. That is, in fact, probably the biggest incentive to try to suck fools into the ecosystem in the first place.
