Is there a plan to reintegrate them?
No reason to do it.But majority can change consensus rules any time.
Yes, lost coins are lost coins. Nothing you can do about it. Bitcoin is divisible to 8 places so there is plenty for everyone. Why we wouldn't be talking in satoshis term one day, not in Bitcoin terms. 1 satoshi can be worth $1 and everybody would be happy.
I don't think so, and that's exactly why I opened the thread.
If the whole world will ideally begin to use Bitcoins, there won't be enough for everyday use.
1 satoshi will end up worth 100$ or so, and you can't really go shopping with that smallest coin.
I repeat: it's NOT an actual problem, but it MAY become in the future, even more when we consider that with time, Bitcoins are lost inevitably in different ways.
So the count is not even on 21 millions, but less.
My friend, let's just hope that we will encounter a problem like this in the future, that's all I can say!
Ye let's hope this and then just add 3 zero at the end, game done!
