Supervising rack access and/or using physical barriers was one of a list of different reasons for why the cost per 1U is so different if you buy 1U rather than a full rack. It may not be the most significant one, but it is there.
As for power, and network, it's often charged separately, and you will still find the 1U vs. full rack difference then. Sure, you can to some extent perhaps assume a slightly lower load factor for customers that rent a full rack, and that may contribute too.
But the point remains: The person above me should not be surprised that renting space by the 1U slot is expensive.
