You have some points, BUT
Actually "anyone can make a crypto" is true
Is it worth then, it's another question.
Bitcoin Cash is the 4th on total market cap with 44B! I don't see how this isn't "didn´t materialize at all". SegWit2x was attempt for something different. BCH is pure
fork.
My conclusion is that those who hate crypto will ever do it and you can't "Debunk" their mind-set.
