Those analogies are retarded. Hammer manufacturers and machete manufacturers have made profit off of every single tool sold, even the ones that eventually wound up in a crime scene. Additionally, the thing about the machete manufacturer adding some safety net sounds similar to how regulators want financial institutions to use the safety net of KYC/AML policies and licenses. You will recall however, that the regulator in charge of issuing money transmitting licenses for financial institutions, FinCEN, was approached by federal prosecutors and asked specifically if Samourai Wallet would need a license and the regulator explicitly said "no". The prosecutors indicted the developers for conspiracy to operate an unlicensed money transmitting business 6-months later anyways. You give far too much credit to this idea that the average Joe is going to somehow dismiss the prosecution's arguments if profit wasn't an element, yet you are neglecting to recognize that the fact that profit was involved was not an issue for the prosecutors as they would have prosecuted them the same anyways. Not to mention, if you listen to the full story you will hear Keonne explain how difficult it is to get defense evidence in front of the jury. You seem to have this common misconception that both side of an argument show up and lay out all their evidence for a jury to decide and that is simply not how it works in reality. Furthermore, you seem to think that Samourai Wallet was raking in exorbitant amounts of money when in actuality there was $6.3m earned over the course of 10-years; so if you take the government's own numbers as true then that means Samourai Wallet earned a whopping 3% of the 2 Billion dollars in "unlawful" funds that flowed through Whirlpool, meaning they are either awfully bad at being criminals or the fee was actually there as a Sybil resistance measure, not a mechanism for profiting off of crime.
