Tokens-as-a-currency is an example of this saying. Sure, they theoretically can be used for some benign legal uses, but technology and implementation is so bad that in practice it is never used as such (I repeat - for completely legal purposes). Most of the people using it are breaking some regulation or laws. Some people break laws in absurd amounts, stealing real money from the governments and funneling illicit gains into offshores.
So while most people can't formulate their aversion to the tokens, I think this is the subconscious reason for it - we are observing an unregulated anthrax in the financial world. The world which is corrupt and dysfunctional as is, but tokens destabilize and corrupt it even more now, making live of people shittier on average globally. And of course environmental aspect too.
It's not. It's a technology with big societal costs and few benefits.
