You understand that the only part of our binomial classification system that can even
maybe be said to physically exist in nature is the "species", right? That genus and up is basically arbitrary bookkeeping?
Try not to fall into species essentialism. Chimpanzees aren't in the genus
Pan because they contain some essential
Pan quality; they're in Pan because that's where some biologists decided to put them. (There is, in fact, a pretty good argument to be made for reclassifying them as
Homo troglodytes.)
