Yes, there are always ways around the problem. However, it is very hard
to find such a problem, especially if the ontology gets big or you're
reusing someone else's ontology (and that is what the Semantic Web is
all about; reuse).
Another problem with your approach is that we have to construct a new
property for every class which uses the property.
