All these arguments are true and we still ended up with VHS. That Betamax was objectively better on every front but one did not matter because that one front - the ability to fit a 2-hour movie on a single tape - ended up dominating the market. A Blu-ray player has the physical capability of playing an HD-DVD. It won't, though. They even use the same codec. It's arguably a superior format in many, many ways and the manufacturers could have made a device that played both - nobody did but Samsung. It was argued backintheday that Microsoft and Apple picked opposite sides on that battle for the express purpose of making sure neither format became dominant ahead of streaming because physical media was in neither of their business plans. Sho'nuff, Silverlight is the backbone of internet streaming and Quicktime has been canonized into FCC broadcast rules. A rational market would choose Ethereum. Markets are rarely as rational as we think they are.
