I pay for all my drugs and hookers with FRNs.
Wal-mart isn't going to accept bitcoin, period, until after a monetary revolution. It doesn't matter if the top ten google hits are "Good Christian Soldiers Doing God's Work Need Your Bitcoins" or "CL Hooker accepts Bitcoin." or "Evil Agorist Tax Dodgers Use Bitcoin." Wal-mart doesn't accept Paypal AFAIK.
It's akin to saying that Hollywood studios aren't going to produce DVDs or Blue-Rays becase the porn industry adopted and pushed them first. (Along with everything else) It's absurd, and far from the point. Porn sites accept Paypal too, you know, along with every other shady enterprise.
I guess this is the hardcore agorist in me. I honestly don't care if Wal-mart accepts bitcoin or not, and I do not believe that it should be a major focus of bitcoin at large. When the time comes, Wal-mart will have no choice.
My .00002 BTC.
I don't think porn sites do accept paypal. Not because they don't want to, but because paypal has been known to freeze and seize their accounts. Paypal sees themselves as a moral arbeiter and won't allow the purchase of tobacco or alcohol with paypal. I am pretty sure they also don't allow porn.
