*I believe virtual particles exist for a number of reasons, the most important being experiments insist that they do. If you assume that virtual particles are real you are then able to make the most precise theoretical prediction not just in physics but in all of science, one part in 10 trillion. The theory of Quantum Electrodynamics, which is about virtual particles, predicted that the electron's magnetic moment should be approximately 0.001,159,652,181,643, the most accurate experimental measurement says it's approximately 0.001,159,652,180.*
Virtual particles are just part of infinite series expansions of Green's functions in Feynman diagrams QED. Your assertion is like saying some term in the Fourier expansion of a square wave exists.
