I think you've picked a poor analogy with regards to email. It's actually the perfect analogy for a distributed social network. With email you can host your own, use your companies, use a free provider (hotmail, gmail, etc) or use your ISP.

It's not possible for one company/person to get across all your email because you can have it somewhere else. It's not possible to store Facebook info outside of facebook.

I imageine a distributed social network being a woven fabric where some people host their own, some use their companies (think bands using their labels server), a lot of people use free ad-based services (think hotmail or yahoo diaspora). However, no one company would ever have all your data, and couldn't hold it to ransom, assuming some type of export facility is built into the design. For I can import all my emails into a different server, but I can't export all my facebook data. Once switching costs are reduced to negligible, then competition for features, usability and, yes, privacy, wins out. Same way as plenty of people decamped hotmail and yahoo for a shiny new gmail account when they had better featurs and an import facility.

Sorry, what was my analogy? I'm saying distributed social networking should work like email and you just described it. However what I don't think it should be is decentrAlizing down to the user level. Another problem with standardizing the system is that new or special features will not be cross compatible, however that's another issue for another thread.
