Just the words "web hosting" are not in most peoples' vocabulary.
You are right that it's good to teach people computer literacy. But your belief that people can somehow spontaneously learn about web hosting is unrealistic.
People first need to experience something, then get some language for what it is and how it works, and only then can they begin to seek out education about how to learn how to reconstruct it for themselves.
Providing turnkey decentralized application hosting is a way to allow people to first experience what it's like to deploy an application. By having that experience and doing it over and over they can start to have shared experiences around it, from which they will learn language about what it is. Only at that point can they start to learn how it actually works and what it might be like to do it in a different way.
She wouldn't have to, it's all about the money and the wish to be dependent or independent. There are web hosting as well as consulting companies that can setup private social network for one time fee, with automated backups and all.
To me, when I hear that some "computer illiterate" person "learns to use facebok" it kinda sounds reminiscent of hearing that someone learns to make crack from cocaine. Is it useful - maybe, is it good for society - eh I don't think so. I rather see them "learn" how to use sandstorm...
