I think most workgroups have effectively been paying extremely high overhead in social costs just so the organization could have the option to organize easily. The problem then is that meetings are called flippantly. If it's hard to get everyone in a room, you'll do a better job capitalizing on when it happens.

The downside is there really are a large array of tasks that a group can tackle better than an individual, but I've never seen a corporate group meaningfully recognize or organize for those tasks. Far more often, I get pulled into meetings because some specific individual or another is lacking in autonomy and expertise.
