I wold just say that i don't need anything which is not available to purchase with bitcoin. Bitcoin is money so i would spend and earn like it, I don't consider it as investment and wait for my expected rate.
Just convert or use bitcoin as it is, doesn't need to give any special privilege or underestimate it. If someone talks about legality
"don't be fooled with that scam", "it's illegal to have/use bitcoin" or other reasons.
I just pity them for having misleading knowledge about bitcoins, since he doesn't know the advantages and how easy it is to to use and transfer without hassle. Sometimes i try to educate him about bitcoins, but most of the time i fail.
