satoshi's vision of having a fixed supply. no more and no less.
I don't see why we should care at all what "Satoshi's Vision" was. He's not a god, and he hasn't been involved in Bitcoin for over a decade now.
However, since you seem to care so much about what Satoshi would think... You're wrong.
6. When someone loses his wallet, will there be a way to recreate the lost coins in the system ? Else the 21 million maximum will not be correct.
6:
Those coins can never be recovered, and the total circulation is less. Since the effective circulation is reduced, all the remaining coins are worth slightly more. It's the opposite of when a government prints money and the value of existing money goes down.
(emphasis added by me)Clearly, Satoshi INTENDED for lost coins to remain lost, and was NOT in favor of reassigning that value.
