Maybe the issue isnt the platonists but the physicalists. I suspect platonists would be happy with their own domain. The issue is physicalists want a privileged quantifier E_physical, and they want a hierarchy of quantifiers where everything reduces to E_physical. Ie., E_mathematical is "really just" a subset of E_physical. The worry of the physicalist is that Ex means x has spatiotemporal properties; so '2' has to "be somewhere".
