I've visited the Chi Omega, Kappa Delta, Alpha Omicron Pi, Alpha Delta Pi, Phi Mu, and Delta Delta Delta headquarters. I thoroughly enjoyed visiting all of them. I hate the idea of not having a central office, especially being able to see the museums/archives.
I see both sides. It would be so much less expensive to run the overall organization without having that physical space. Similar to the question that many corporations are facing right now- keep office space that the last three years has shown isn't really needed? or try to maintain that brick and mortar presence?
