Of course I have. I have no idea how you are concluding that.
So, I should have said "every structure that stands alone is one or more buildings." How's that?
There's the usual divisibility question here, in that if you take a structure and mentally divide into two pieces, you have two structures. But when I say "a structure" I mean a maximal connect component of such, not just part of a structure. The same would apply to "structure that stands alone," and I was assuming such maximality in my previous statement.
As to "stands alone" I take that to mean that there's some region around the boundary of the structure that is devoid of structures, and if we removed all other structures outside that region our structure would be unaffected in its stability.
Anyway, the NEC definition of building is goofy, as if I drive an isolated wood post into the ground, that's a building.
