We trust the government to regulate and control all sorts of things (tv, radio communication bandwidth, some local utilities) I don’t see why having some sort of oversight and rules governing what Facebook can do with data it collects is a problem. At the very least guaranteeing consumers access to all the data Facebook has about them could be a start.
All of those examples you give are a) easily identifiable (e.g you are transmitting on a particular frequency) and b) scarce due to very high barriers to entry (e.g betting a power utility).
Web sites are different. Facebook is just one end of a spectrum of thousands, perhaps tens or hundreds of thousands of electronic destinations that come and go, and cost a few bucks to operate.
Regulations aimed at Facebook would potentially end up targeting every web site with user generated content.
