Of course, because communication is expensive (as in time wasted, brainpower wasted, decreased focusing-ability etc.). But I think they get it wrong with meetings: A few time boxed stand-up meetings are great instead of "full-time IM-ing" for distributed teams or "anytime possible interruptions for collocation ones.
I think the OP dreams of an "interrupt-less" work-mode, as opposed to the "interrupt-driven" ones most of us have now. In this view, rigorously time-boxing communication would serve the purpose better than avoiding all meetings.
