Walmart Supercenter buildings are distinct semantic entities that can be tied to a well defined geometry.     The solar panels on the roof can be attributed to Walmart inc and estimates made of their output.   The loading docks on the boundary of the polygon can be counted and assessed against the floor area and local road capacity.   The subway inside the store is semantically inside the store instead of merely near the store. 

I have been modelling the world in a manner that uses the expressive power of the medium to enable the best geographic inference.  

I am sorry, I was not aware of a local norm mandating all point venues.  If you would like to give  me a bbox delineating the area of this  convention I will avoid it in future.
