I think part of the problem is that mining was a very clever solution to a logical puzzle that seemed impossible to solve. Like bloom filters, it's tempting to find a use for it, because the algorithm is so cool.

However, the theory and practice turned out to be very different. Neat algorithm can't be used as an excuse for the whole ecosystem that emerged around it: insatiable electricity usage of PoW, pump and dump, ransomware, money laundering, etc.
