Bitcoin isn't for everybody.
Who says so? You? Why? Bitcoin IS for everybody, but we just need to agree on how it will be done. (everyone directly on the blockchain or via some other way like sidechains). If
you state that "Bitcoin isn't for everybody" I can easily state that "Bitcoin isn't for you" because
I want it so.
It just kinda can't be for everyone, because of the way that people are. The majority are sheep and/or dogmatics. Often, you can't even reason with them. The idea of Bitcoin is about 100 quadrillion light years away from their 'in the box' thinking style. Also I often get the question: 'why should I, there is already fiat?'...
Then again, what does the 'Bitcoin isn't for everybody' discussion have to do with the fork?
