The REV debates are completely missing the point. Of course revenue for chains (like any business or protocol) are important. It isn't the only important metric but it certainly IS an important metric. The thing that the REV maxis are getting wrong is that REV is only as good as you can project out its sustainability. The things most blockchains do poorly is retaining earnings for growth to invest in trying to sustain REV. If there is a lesson of the challenges that Ethereum has faced it is that it generated billions of dollars in fees over a multi-year period and it couldn't sustain it because there was no mechanism to reinvest in its success. I believe @arbitrum is the furthest along in trying to solve this, and that's why I believe it will be the world's largest digital sovereign nation.
