It's not accurate to say that a big thing for us BTC users is anonymity. That may have been the mantra years ago but it's at most pseudo-anonymous today as those holding and wanting to cash out significant amounts of BTC will realise now with the majority of big exchanges requiring ID verification.
Dark markets? Guns? Drugs? I'm almost certain most of us have never whiffed a puff of weed or held a gun bought with BTC. =)
