I don't think common people "should" use Bitcoin right now, it's very complicated for most, specially women and not tech savvy people. I don't want to sound harsh but that's my experience.
I understand you. And I kind of think that too.
If I introduce Bitcoin to my mother, brother or other people who aren't tech savvy... They would simply forget about it because of many things: bitcoin is not so easy to get, it is confusing how to start using it, create wallet/address or whatever.
Even paypal is not that popular in my contry, and it is still hard to find local online shops accepting it let alone Bitcoin.
I remember while in school we all had those lessons with fiat currency, we had fake money and coins made of paper. Their purpose was probably to teach how to deal with money and bla bla bla...
I think it is time to teach them how to use Bitcoin too.
