So you'd say tough luck to them but to people irresponsible enough to lose their coins, zomg we need to reclaim them!
If you actually read and understood what I've written on this thread then you would know that I DON'T consider lost coins an issue. In fact I even demonstrated this by calculating for you the number of coins remaining after 170 years of loss at 2%-- there's plenty left at this stage. What you've quoted above I wrote in response to something else, not lost coins!
In response to what you've written: It would be very difficult to add more decimal places to the coins in the bitcoin network itself cause this requires a hard fork. However to allow trading in sub-satoshi unit is trivial to do in other ways. For example, a bitcoin bank could just staring minting electronic tokens or even real physical tokens (coins/notes) which they claim are backed by bitcoin-- eg: they print 1000 X milli-satoshi tokens every real bitcoin they have. For course, they could even print 2000 x milli-satoshi tokens for every bitcoin they have and hope that not every one tries the redeem them at once (ie: they recreate fractional banking).
(I'm expecting you people here to start trashing me at this point-- but the argument still stands and it is impossible to stop a such development if bitcoin heads in that direction.
By-the-way: I not saying that you should do this or that it will happen, just that it can happen-- but I'm not hopeful that you'll understand the difference. I've witnessed enough on these forum-boards to realise that it doesn't matter what you say, when people here read something that they don't like or can't comprehend, as a knee-jerk reaction they assume that you support it and must therefore by the part of some-great conspiracy to destroy bitcoin.)
