OP, you are spinning this and putting words in Peter's mouth.
What he said is when the mining reward goes to 0 (in the year 2140),, its unclear what happens with the natural fee market.
No one in the BU camp is saying "we need to change the social contract and have more than 21M coins" which is what
you are implying.
Bitcoin will have a non-zero inflation rate for the next 120 years. And we could always decide to re-introduce the protocol enforced limit at that time if no other solution
is available.
Ridiculous denial. This
effectively means that the total supply will be no longer 21 million coins, because BUcoin is in a dead end eventually.
Are you myopic enough to not see how a vast amount of BTC investors get on bitcoin precisely because of that certainty of the 21 million coin limit as they run away from inflationary currencies/assets and want digital certainty?
