Intentional consealment of illegal internet traffic isn't a crime (the crime is just the crime).

Intentional consealment of illegal financial transactions is a crime in-and-of itself (the crime is money laundering, which is a seperate offence to the original criminal activity that the money came from).

Well it is a crime to use it for obscuring illegal money, while it is not illegal to use Tor for obscuring illegal internet traffic

conspiracy to commit a crime is often an additional charge (IANAL)

That’s just when two or more people get together to plan a crime - obfuscation isn’t the offence, the offence is the joint planning and intention to commit a crime.
