Also, your point on BTC being used to buy a joint, you said something like it's only the last thing in the production and distribution chain, implying that law enforcement is doing something wrong. BTC is used for something illegal and thus should thus be persecuted, just as any other part of the chain. Sure we are making progress on the decriminalisation of cannabis, but your point is not very good.
I thought it was an apt analogy. In context it made perfect sense. BTC is too easily (lazily?) persecuted for its anonymity and the attendant connection with Silk Road, et al. And yet every part of the supply chain to the point of those illegal goods being offered for sale has been funded using a fiat currency.
By extension, you can't knock any form of currency because of the questionable ways in which an immoral minority will use it. That's like saying you can't sell cars because some people will drive outside the regulations. Perhaps you misunderstood?
