Some people think so; that is why the popular term for mathematical
realists is "platonists".  Plato's Forms were ideal exemplars of
mundane objects; sets do not have this character (the set of all
natural numbers is not a perfect natural number).  There is a
relationship between sets and form with a small f (to avoid calling
the objects of mathematics "abstract", which I think is
epistemologically misleading, I call them formal objects), but they
are not Forms in Plato's sense.  Moreover, the use of mathematical
objects is quite different from that of Plato's Forms.
