Matt's reply here is a commonnin defence of drivechains that is good, but not my favorite. It's one of the weaker defences, and only weak because of the counter position of most maxi veliefe that bitcoin number go up.
Claiming miners will need fees when your debate partner believes future miners will always make sufficient money of blocks because fiat will simultaneously lose value alongside it is not how bitcoinnwqs intended or designed. So if they do not know this or are ignoring it, i prefer leading with the stronger more universal reasons.
>Maybe mining wasn't supposed to be mostly centralized corporations. In concept.
>Satoshi intended plebs to mine off CPUs.
I cannot know the mind of satoshi or his intention. Perhaps he saw the present reality or not. He's not god or a parent i am supposed to carry out their will for. He was just a clever engineer who in cooperation with many others and their inventions, created bitcoin. Also, he intended fees to secure the network long term, the security model relies on this, from his perspective vased on the whitepaper of 2009.
We must deal with present reality. For instance, by your reasoning we should switch to Monero. It uses RandomX which eliminates ASICS completely and allows any regular laptop to secure the network. Switching to randomX (but not monero) happens to be one of the emergency measures that could be taken to circumvent a state level 51% attack by the way.
>In theory, is changing the Core code good for the money itself?
In theory and in practice yes. More intrusive and disruptive bips have been passed before. Bip300 will have fewer affects than taproot, simply because the affects are designed to be isolated to those who want to participate.
>Mining will be fine, as difficulty will adjust. Same security.
Maybe it will but the difficulty adjustment does not pay more money to miners or incentiviseS a dencentralized hash. I find miner arguments againsy DC to be a distraction. DC plays by the rules and dynamics that exist. Miner decentralization is an important issue and there are other projects trying to deal with that. But this bip is about sonething else.
I hope this comment was relevant, i did not read the ones further up the line.
