> There is no official bitcoin blockchain.
Let's just say there is consensus over what the Bitcoin blockchain is, versus whatever the "Bitcoin Cash" or "Bitcoin ABC" blockchain is.
> There is only the chain with the most accumulated work, and orphan chains. Anybody attempting to remove a limit which may cause the holdings of all bitcoin users to be devalued will simply be ignored by all other users.
Most users of Bitcoin perform no work whatsoever. Miners perform the work. Users can't ignore the interest of miners, even if miners are a tiny minority. Miners may not even have any holdings.
A core value proposition of Bitcoin is that it's the "most secure" network. If a majority of hashing power is priced out of operation because of low block rewards and low fees, that security flies right out of the window. This situation would have a far more significant impact on price than a little bit of controlled inflation.
> To relax or remove the block subsidy, one would need to hard fork the protocol in order to defeat the "less than or equal" check. You would have to convince the vast majority of bitcoin users that they aught to download and install alternative software which may cause inflation and devalue their holdings.
It's not going to be alternative software, it's going to be a software update, through the official channels. It also likely would only affect full nodes, and the majority of Bitcoin users haven't been running full nodes for a while.
It's really up to a few key stakeholders, not Bitcoin users in general. When faced with the decision of giving up network security versus maybe losing a little bit of value to inflation, they will choose the former, because they're not that stupid.
> Keep kidding yourself that this will happen.
A similar thing already happened with Ethereum, the rules were changed mid-game in the official client, the loser fork (Ethereum Classic) was the one that kept the old rules intact.
