BTC will benefit from ETH’s rally through WBTC, If the Merge goes well and the Supply Shock kicks in. Do you agree?

Was just debating with a friend about this. He claims instead of the rest of crypto 'decoupling from BTC a few months after the merge and when ETH begins to rally due to the massive supply shock, ETH will rather save the entire crypto market including Bitcoin through WBTC on the ethereum chain. Thus if there're no black swan or any unforseen macro events. Thoughts?
