Facebook isn't any different to any other capitalist enterprise - the advent of the railways sprang to mind when I read this, and mass industrialisation generally. It's the next wave.
Governments are helpless because they know very little about what's involved and the implications, the parlous questioning of Mark Zuckerberg by US Senators illustrated that.
As well as the very aggressive monopolising, Facebook is adept at exploiting addictive tendencies (you've written elsewhere about this) and we are very poor at educating children and young people how to manage this still relatively new social environment.
