Indeed they are... As is the case with any anonymous currency (like USD bills) any transaction that 2 parties find agreeable would be performed. This might be swapping cash for tomatoes from the farm, paying your doctor, a blowjob from a prostitute, a gun from a criminal or drugs from Medelin cartel. When there is a system of transact after approval of the counterparty (like in the banks) you'd find less criminals using it, because of the risk of losing the money and tipping the law enforcement. However, when the rules/law enforcement are bad permissionless transactions are a godsend as cryto usage in Venizuela shows: https://www.americaeconomia.com/en/node/288189 https://www.americaeconomia.com/en/node/288189 Also, when the governments print money and debase the purchasing power crypto is indeed a better store of value than something like argentinian peso. Freedom is messy, because the bad guys are also free to do bad stuff. But when the game is crooked, permissionless transactions are very important.
