Buildings are a bugger

As I flit like a bee from one big organisational headquarters to another it occurs to me that such buildings add little benefit and restrict in the following ways:

    You have to waste time, money and energy traveling to them.
    They cost a lot of money to maintain.
    You are subject to IT networks that are slower and more restricted than your own at home.
    You have to pretend to be working even when you are not whereas elsewhere you can stare out of the window and think.
    You are less in control of who interrupts you and why.
    Their architecture is often depressing rather than uplifting.

Can you think of any more reasons?
