Replying again as I did some research. It turns out there aren't actually only 13 root name servers, there are almost 2000. Also, the vast majority of queries to the root servers are from badly configured systems that aren't caching results properly or aren't even receiving the results. So running your own caching resolver, assuming it's working correctly, would contribute to the small drop in the ocean that is legitimate usage of the root servers. Presumably the same applies to the next levels up too.
