True. But in the case of _Ceratops_, this was inevitable. _Ceratops_ is a
lousy genus to anchor a clade in, irrespective of whether it's a nomen dubium
or not. _Ceratops montanus_ may be a nomen dubium; or we may be able to glean
enough characters to diagnose a valid taxon. Either way, _Ceratops_ is a crap
genus to name a whole family after.

Of course, these are all judgement calls. The issue boils down to this: Do you
think a given genus is sufficiently well-known to be the name-giver for a
clade? This is when experience comes into play. Experience should be the
principal arbiter of naming clades - instead of citing ICZN rules about
this-or-that family having priority because a 19th century paleontologist
erected the family 150 years ago.
