It's not for you to decide what would make the life of other people more comfortable.   Bitcoin does need this kind of proselytism.

Do you know that there are a lot of people that know that bitcoin exists, and yet reject the idea and don't want to use it?  If one of this person happens to own a commerce, you might want to buy stuff from him anyway.   Thus you'll have to exchange some of your bitcoins against USD/EUR/Whatever.   And to do so  you might have to use the banking system.
