An interesting idea, it reminded me of Name Coin basically bitcoin but for a decentralized DNS with a token system a copy of Bitcoin - I imagined many blockchains for different applications the only difference was they would be Merge Mined.
I suspect given some overlap between BTC and BSV and the need to pick a chain to mine (opportunity cost) that over time miners and users will converge on the best overall package. For now, I think what's happening is possibly the optimal path for success.
I do think this is going to be the biggest wealth transfer in history but, I don't think wealth is going to be concentrating in the hands of the wealthy as those who have access to free fiat buy-in to BTC fuelling the adoption mania. I think there's a probability there will be an awakening event after BTC is hyped, where the masses slowly or quickly shifts to a blockchain that works at scale as sound money for people. The SoV wealthy elite who owned most of the BTC will double down on their SoV narrative and "use our digital gold" market pitch to back "out payment network" while the masses move, to hard money that delivers value.
Ultimately Gresham's law will take effect, and BTC loses its lustre due to it being "gold 2.0" while people build the network effect on BSV or BCH, heaven forbid some other blockchain.
