Arguably, people don't even realise that they actually need something. You know the amount of people I hear slagging off banks, and not trusting them? Then they're ignoring that there are alternatives despite saying "But we're forced too". People tend to just follow the trends, we are very much sheep penned in most of the time. I know its a hard thing to accept, but we've become pacified to the point where we actually believe we need x service, and y service. Sure, some people genuinely like the convenience, but I bet if you asked the majority of people without mentioning Bitcoin if they would like to be in full control of their money, without relying on third parties the majority would be interested.
Bitcoin unfortunately has been dragged through the mud, and therefore there's a negative stigma to it.
I guess? Totally depending on what the certain "thing" is. But at some point if it's the case that the "thing" is totally needed and/or they're forced to use it, then they should use that "thing" even if it damages their egos. If they still don't, then Darwinism should run its course.
