 If Ethereum is really trying to be something different from Bitcoin, why doesn’t the Ethereum network use Bitcoin as the base currency? 
 i think ironically ppl are trying to do that now with bitcoin l2s that intend to run evms (eg alpen labs). still hard to build a trustless two way peg (bridge) without softforks. so the short answer is that currently a trustless version of using bitcoin as the base currency of another chain is just not possible.
