I didn't make any claim about "simplicity", and nor does anything in the link contradict anything I wrote. Indeed, it confirms my point: some things take "the", others don't, and it isn't a matter of on-the-spot whim.

Note that I did not propose any general rule for determining which category something falls into without prior knowledge. My comment about descriptions versus names does not have any predictive implications. I could have talked about "weak" and "strong" instead.
