- Phone scammers are running rampant. We don't ban phones.

- Spam has been a problem since the inception of email, and the majority of email is spam. We don't ban email.

- Baseball cards are similarly pointless. So are in-game cosmetic items. We haven't banned those.

The problems you're describing are mostly unrelated to crypto, have existed, and will continue to exist whether crypto remains.

This doesn't mean there are no valid criticisms of crypto - energy concerns are real, and need to be addressed - but if you wish to ban crypto for the reasons you've cited, you need to widen the scope of what you hope to ban.

Out of those things cryptocurrencies is more likely going to be banned anyway, only to be used for illicit activities.

Are you claiming that crypto is only used for illicit activities? Care to back that up?

Not just that, there is speculation, gambling, etc. with those two being the most used usecase, nothing else.

Once banned that is where they will reside, I hear that Monero is thriving in that (illicit) environment, as well as Bitcoin, Ethereum (paired with Tornado)

But for now banning is likely.

>nothing else.

Come on. There are people in this very thread who are using it to evade draconian currency controls their governments have imposed.
Are they lying?

Whether the positives outweigh the negatives in Crypto is subject to debate. But to refuse to acknowledge that ANY positives exist is outright bizarre.

There are lots of things I strongly dislike (eg: religion, guns) but to insist that there are absolutely zero positive aspects to these things in certain contexts would be intellectually dishonest.
