That’s a purely technical perspective on the situation. One could make the same argument about gRPC versus SOAP versus XML.
What would have been a more constructive response was:
This looks like JPMC is trying to profit off hype by building a new accounting and settlement system on blockchain. Since they control all aspects of their network and ultimately are the only one redeeming tokens for dollars, they could have used something simpler. However, I bet they did it this way because they think forking ethereum is cheaper than building a new system from scratch and also they might get a bump in stock price from the hype. If they built and announced the same system using bespoke tech (that likely solves the problem more effectively), no one would have probably cared.
