> To that sense, it's really just a disagreement on what tradeoffs are acceptable. People who have a utopian view of cryptocurrency are looking at some tradeoffs as preferable to others, it's a different failure mode.

Another way to restate my comment is: cryptocurrency is technically interesting but the tradeoffs it made to focus on certain edge cases mean that for pretty much every use-case, the preexisting technologies are superior and/or cryptocurrency is practically unworkable.
