I suppose it is possible that many people find a system with some inefficiency to be practically nicer, easier, and more functional than one with absolutely perfect utilization, allocation, and efficiency.

efficiency in a systems problem is almost never easy, and it requires everyone who participates to put forth their fullest effort. It is telling to me that when people are unconstrained by space/cost/time, they don't tend to create extremely efficient situations, but in fact prefer those that intentionally less so.
