One can think that all mathematical objects are ultimately (modelled as)
sets without thinking that all effective mathematical methods are set
theoretic methods.  Compare:  one can think that everything studied in the
sciences is ultimately physical without thinking that the only effective
scientific methods are those of physics.  Who would expect botanists or
psychologists to use the same methods as physicists?
