While I'm personally not a fan of the outcome of Citizens United, the argument that a company is just a collection of people is not unreasonable to me. What makes an individual any better at acting as social glue than a collection of individuals? I'd argue a collection would serve much better, and really it's more the for-profit nature of most companies that is the issue. There's no reason a company has to "maximize the value for shareholders", and it seems more and more companies these days are challenging that notion.
