Both forks would exist alongside each other - the conservative / purist one and the 'fair' one, and the market would choose which to give value to.

"Fair" meaning what people consider fair. Now, generally bitcoiners consider it fair that those who work hard and spend less should be wealthier than those who work less or spend more. So in extreme cases, the archeologist's Cantillon effect-driven wealth would be viewed as extremely unfair.

Now I may be going off on a tangent, but there are many other ideas of fairness. For example, socialists might prefer a coin that results in a more equal wealth distribution. E.g. a Bitcoin-like network that airdrops money into your wallet every month and expires it if you don't spend it, to prevent accumulation. And these ideas of equality are quite popular if you look at politics. This can easily be achieved with a CBDC, but can they materialize in the form of a decentralized network like Bitcoin? I can see a hurdle here, namely it would have to ensure one person can only have / control one wallet, which would require a system of centralized identity issuance. Even if it's possible to overcome these seemingly technical obstacles (which may actually be more fundamental than technical), another question arises: who decides what money gets adopted and gets to dominate? Is it those most able to accumulate wealth after all? They surely would milk their SocialistCoin airdrops by selling them for BTC as soon as they land in their wallets, transferring value to what allows one to store value.
