I don't understand some of these rules that can't be enforced, such as "only one utilization equipment can be plugged in".
There are others.

There were rules prior to the 2008 code that would permit you not to have GFCI where a single receptacle supplied specific appliances in areas that would otherwise require GFCI protection, but they didn't not require a single receptacle. The use of the single receptacle was optional to avoid installing GFCI protection.
