privacy isn't really a market power problem though, because you can have a market in such data. We need comprehensive laws protecting privacy before an agency can enforce them.

If social networks are centralized then the operators can do anything the law allows, including invade your privacy, and you can't get out of it because of the network effect. If they're federated/decentralized then you can choose a node (or operate one yourself) that contractually or technologically guarantees that it respects your privacy, and then people would pick those because they don't want their privacy invaded and they would have the choice.
