The biggest thing for me in this whole equation, is that Steem-Engine is here, and working and doing things. It has been implemented. People are creating tokens. And people are using the creation process and market. Steemit/Steem always seems to have been long on promises and painfully short (and delayed!) on actually delivering on those promises.
So beyond the valid points you bring up, with every day that passes Steem-Engine establishes a little more of that "First Mover Advantage" which tends to have a more far reaching impact on the business world than most are willing to give it credit for.
