It's more like "don't install that library, we can just write a 10 line function." Someone who doesn't want to avoid the law is not going to get any of the benefits of using a cryptocurrency. It's a solution where the main use case is enabling people to make currency transactions outside the jurisdiction of banks.

I think there are some good use cases for it, like if a currency is unreliable due to corrupt government or inflation. However, the people who get the most use out of it is certainly ransom ware coders, people who distribute illicit goods like drugs and child pornography and finally libertarians that want to make themselves sound clever at a party.
