Fuck you very much, sir.
I, and the vast majority of Bitcoin users, engage in entirely legitimate commerce with BTC as the medium of exchange. Heck, I even declared my BTC gains on my taxes last year, fer chrissakes.
Now, when I want to score a quarter of weed - You ever actually try to buy anything with BTC, or just mindlessly parroting the FUD about Silk Road? My dealer takes USD only, thanks.
