This isn't restricted to "offices." It's also why it's difficult to live with other people and housemates often end up in conflict. The more people you need to share a space with, the more contention each shared resource gets, and fewer individuals get what they actually want when they want it most of the time. There's tradeoffs to make, of course. We have societies and communities precisely because groups tend to accomplish more than individuals thanks to specialization and division of labor, but there's a reason humans tend to live in roughly family-sized units when given the choice, not open dorms with hundreds of other people.
