After all, quasi-particles are not virtual particles. Let them turn up. Suppose matter has a fundamental particle (which can be very much lighter than any quasi-particle observed), then, any number of quasi-particles can be formed from them. But, the natural choice for integration (for some hitherto unexplained reasons) are electrons, protons and neutrons. 'Better humanize than demonize', I would say. If the evolution of physics goes in the direction of QM, it will create incomprehensible monsters. Perhaps that will the end of the Jurassic period in physics. The monsters will all of a sudden disappear - an evolutionary disaster.
