I disagree with your first point mainly because this is more of a symptom of what Americans want, not necessarily some sort of virtuous result of the banking industry. I'd also argue that it doesn't "make our entire economy run." What makes the economy run is people going to work and performing work, producing goods and services. Banking is merely an aspect of that, and it's perhaps propped up into a bigger piece than it may need to be because people prefer being able to (or in some cases need to) access credit to buy stuff. I also somewhat disagree with (3) because it's ambiguous how many people constitute these mining facilities referenced in the article. You write it as though it means 137 individuals. But overall I only dislike crypto because it has become a space for charlatans and people who want to get rich quick. Any original principles behind creating a new currency outside of fiat and actually using that for transactions have been forgotten since then and crowded out by people who pretend those principles still mean something but really just want XCOIN to moon.
