"Lots of stuff is bad and so all of it must be bad" is a weak argument. Look at email: 85% of mail is spam and scam. If you read beyond the hype the use cases are very clear, even if they are very narrow: disintermediation, decentralization, and making permissionless payments and contracts. Blockchains like Monero and zcash are pretty good ways to handle anonymous payments across the world, compared to sending cash in an envelope or trusting a third-party with your privacy. If Tor would be allowed on SourceHut even with its negatives, so should Monero and zcash. Monero and zcash were not built with the explicit goal to scam people, and they do provide features that were not easily achievable prior to this technology.
