I used to send money to relatives. I'm sorry you bought supposedly addictive drugs, and I hope you won't do it again. But "I know one guy, and myself" is a very poor argument when you are generalizing.
Both of them used the same argument, though. I think that bitcoin has powerful uses (e.g., yours), but the majority of people are not using it for transactions. I'm not saying that it's a bad thing, per se.
