I agree.

Thinking about knowledge representation, say we wish to represent a 
non-binary relationship. Then we use blank nodes to construct the more 
complex structures. If we had to name them, these names would be arbitrary 
and we would need some method of indicating that those names were arbitrary.

I think n-ary relationships might have been a different design choice.
