Anonymous crypto, yes.
But if you're suggesting blockchain is anonymous and payments are untraceable, that's not the case for bitcoin at least. It's a gift to law enforcement, if they cared enough to trace btc transactions.
This looks like a case of in theory yes, in practice no.
Tracing btc transactions to real persons can be quite some work and is a new kind of cat and mouse game.
In practice all tokens including BTC are massively used for law evasion. Criminal don't need any fancy Monero for that, they only need to break the chain once, or maybe a few times an that is enough. That usually happens at the entry points, a criminal backe exchanges of any size will happily take your cash or digital money and exchange then for any tokens you like and vice versa. A politician then declares that his several BTC worth a few millions were "fairly mined" and nothing to see there. Or a corrupt government pays with tokens for some sanctioned wares. The whole Axis of Losers trade is propped up by mafia's USDT, which are used to trade between Axis countries and willing collaborators like India, to buy oil/rockets/chips/soldiers/anything, with central exchange in Dubai and other petrocratias.
