You can use ordinary USD (or any other fiat currencies) to "enable" stuff like assassinations and child abuse. All anonymous cash allows that to happen. That's why there are regulations and reporting of large cash transactions. There's nothing special about cryptocurrency there, except that regulators have not regulated KYC/AML enough yet. There's very little "value" in cryptocurrency, there is some value in the concept of blockchains, with proof-of-stake, replacing titles offices and other regulatory registers. NFTs are essentially that, but don't have any legal or regulatory power behind enforcing the "ownership" that the NFT records.
