There will be 21 million ever and he doesn't want any, better that other people have them then, nice of him to get out of the way.
This is a terrible way to think about it. If you do not address the issues merchants are seeing then it will be very hard for Bitcoin to have the wider adoption many hope for. Exchange risk *is* a real concern and you should not shrug it off. Instead we should think about how we can work with merchants and help them understand and manage this risk or even turn it into a non risk.
If you want Bitcoins to matter beyond a tiny sphere, then you have to be ready to solve the problems others are having and not just think about yourself.
I completely agree with all of this - I'm a geek and thus love bitcoins and accept the risks that come with it, how the average folk dont even understand it, they have had there fiat currency all there life, its what they know and trust - if bitcoin is to reach the mainstream, the risks that come with it need to be mitigated or removed completely - otherwise people wont trust it and will stay with what they know, shitty currency thats rigged.
