Pop quiz: Convince an average low/middle class fiat-loving law-abiding person that they should use bitcoin without talking about its price or making profit by trading it.
The people you've described tend to be very very stupid, or at least simple-minded. Sheep in general. They believe that government and establishment will help them out, if they only vote for the right politicians.
They think that the best way to make money is to put it in a bank and lose 3% purchasing power each year, despite interest, or to invest in some conservative mutual funds which won't make them any real profit until they die - at least they can pass it to their children... after a hefty tax.
Or maybe they just love being slaves.
EDIT with regards to your quote - if these people are fiat-loving, then you'd have to change that first. For them, Bitcoin offers no benefits because they love the government and idolize the leaders of their political philosophy in government.
Of course, these same leaders will dump them in an economic crash and tax them into oblivion.
I think the proper technical term is agreeable. It's not something you choose. Just like we didn't choose to be disagreeable.
