Yup. Except straight cash still needs someone to physically collect it which leaves a point of failure in the crime and a good place for authorities to catch the bad guys. Bitcoin removes that.
The very nature of it makes it much easier for criminals to avoid authorities once payment is made though. Sure you can screw up and do something stupid like send it to coinbase and cash out but there are lots of ways to use it without the authorities being able to determine your identity or location.
