As much as I like the fact that Bitcoin has some anonymity built into it, really I am not a fan of the fact it encourages illegal activity. Part of the reason I got into bitcoin later in the game, so to speak, was because of things exactly like this! I don't want to be affiliated with drug trafficking, porn, or even gaming sites. So as much as this probably will help boost the price of BTC, it is actually disheartening to me. And perhaps it does undermine the legitimacy of BTC in the longrun?
I imagine that you can send FIAT by post instead of BTC if you want to buy illegal drugs, porn, etc.
So what, do we get rid of internet because it promotes the black market? Obviously not
BTC is just a currency, you can do exactly the same operations you can do with FIAT, probably much faster and cheaper.
The change has to come from another direction, educating people and adapting laws to people needs, not the opposite
