I am not a PM dogramone but I completely agree with you and for exactly the same reasons - essentially a compartmentalist outlook. Or just mentalist. Also, I'm crap at working from home and easily distracted 🙂

I've found meeting time seems to increase (and effectiveness decrease) with size of business. We just have short focussed meetings here in a smallish shop. I can see though that as we have grown there are more opportunities to get your ear chewed by those enjoying the sound of their own voices.
