This unfortunately does mean crypto is good for moving assets because of it's decentralised and permission free/immutable nature and that's always a tradeoff.
Not all crypto is decentralized and permissionless, you are talking about BTC when you name these features, there are a lot of centralized cryptocurrencies, ones that their issuers can even confiscate funds when it is held in your own wallet, like usdt.
Scammers use a lot of tools to scam people, not only crypto, i know a lot of people like to isolate statistics like this to talk bad about BTC and crypto. BTC isn't even a suitable tool to move stolen funds, because of its public ledger, but many people tend to forget that fact.
