Actually it's the fact that you completely changed your argument that makes you look like you are loosing the argument.
I though we where talking about how easy it was to launder Bitcoin, but I get it that every time Bitcoin evangelists feel attacked and can't really give a proper solution to some problem about bitcoin (the fact that it's so easily laundered in this particular argument we are having) they quickly point their fingers at any fiat currency: "Ei, don't look at us, look at them, look, look how money is also evil." while failing to address the issue at hand and trying desperately to compare apples an oranges.
Yes, because any reasonable person understand that while fiat, gold, diamonds, etc can be used to launder money, it's actually a process that demands lots of connections and quite a big deal of risks. Unlike bitcoin where you have to just simply pass it between a couple of wallets/websites. But oh well, I quite used to this kind of ridiculous arguments from bitcoin evangelists taking place on Reddit anyway.
