Aside from that such change would require a hard fork it also violates one
of basic rules of bitcoin, which has long term consequences for miners and
for whole Bitcoin economy. In short, after altering the supply limit it
would not be "bitcoin" anymore.

This topic has come up several times in recent years. While it is well
intentioned, it can have devastating outcomes for people that want to save
long term. If such a system were implemented, it would force people to move
funds around in order to not get nullified. In that process, it introduces
multiple opportunities for errors. Cold storage should be able to stay
cold. I personally would be apprehensive about implementing this kind of a
system.


Furthermore, if it rewards miners with funds that are expired, it creates
terrible incentives. Miners in their best interest could choose to censor
transactions that move funds close to their expiration time, to increase
their own future rewards.

Hi,
1. If there are 16.4 million mined and 4 million are lost, that results in
12.4 million in circulation vs 14.4 million.
2. Satoshi addressed this as have numerous other people (
https://bitcointalk.org/index.php?topic=198.msg1647#msg1647 ) - lost coins
decrease supply, increasing value of the remaining coins.
3. This assumes this is a problem.  Bitcoin is divisible, 100 million,
potentially more if necessary. (
https://en.bitcoin.it/wiki/Help:FAQ#How_divisible_are_bitcoins.3F)
4. Why is it okay to steal bitcoins from people who's bitcoins have been
"dormant" for a fixed period, 10 years in your example?
5. What happens to bitcoins that, say, Hal Finney still had (if any) and he
put in cold storage while he is in ultimate cold storage (
https://en.wikipedia.org/wiki/Hal_Finney_(computer_scientist)#Death) ?
Ditto for someone, say, in a coma for 11 years, in jail for 11 years or any
other similar event?  Or a 20 year old sets aside coins for retirement.
The following year, the system is changed, and when he looks again after
not paying attention for a decade or two, they are gone.
6. This encourages censorship by miners for people attempting to move coins.
7. This has been discussed many times before and everyone is welcome to
fork bitcoin code and the block chain and convince people to follow this
chain and code.  Then you can see if you can get many people to agree that
this is a good idea.
