I think what people miss most often is that this is NOT a "one solution fits all" kind of thing. For some office cultures one is better, and for some people one is better.
I myself am very easily distracted, and I'm far more productive at home, where I have a private office set to my preferences, including sound (this sounds ridiculous, but my ear cartilage is sensitive, so I can't wear earbuds and over-the-ear headphones are only comfortable for an hour or two), light (most offices I've been in have had times of day when the sun causes painful glare), and lack of people moving around distracting me. And that doesn't even cover whether I have to listen to the conversations of dozens of people around me.
I don't like being loud and distracting to other people, so WHEN I talk to co-workers in the office, it's either in a meeting room, or in clipped, hushed questions. I have one teammate that has a rather booming voice and no apparent concern for who hears him - I just decide not to ask him questions.
Meanwhile, my current office has people in 3 states (2 neighboring time zones), so we have a culture of lots of business being conducted over slack or google hangouts. One of my coworkers and I have conducted a lot of business over slack...while sitting next to each other.
In talking with others, I've discovered that some of us (including me) PREFER to conduct business over written media -it gives us something to consult later, and requires that people learn to not play the pronoun game. Others, perhaps because they either haven't figured out the pronoun game, or they really hate it, prefer face-to-face, which I've always found to have a poor signal-to-noise ratio. (They'd almost certainly disagree - you yourself said that "communication is faster and easier, less prone to misunderstandings, and I believe that's true for you despite each point being invalid in my experience).
Every time I or others complain about open floor plans, someone (and it's usually just one or two) will talk about how nice it is to have face-to-face collaboration...and frankly, I just don't see that happening! In my last office, which was open floor plan but had no culture of resolving things online and our other locations were 12 hours offset, there was definitely more face-to-face collaboration - but we also had a lot more meetings (ugh), and IMNSHO very little got done, so I remain unconvinced that it actually is more efficient, I think it may just be more comfortable.
From all of these anecdotes I have assembled my vision that for some office cultures, meetings are better, and for some people, meetings are better, but theses are hardly absolutes, and my personal bias is that it's a war between comfort level and actual efficiency.
