We gain simplicity of argument. The “messiness” of atoms is already enough for my argument that apples as discrete entities exist in the mind but not in reality; the reality of quarks, leptons and bosons (perhaps 16-18, rather than a few hundred particles) is even more “messy”, which makes my argument stronger, not weaker, but also more complicated to explain.
