> This is a nice idea, but this line of thinking will lead to some very unusual results. The most famous is possibly the "ultraviolet catastrophe" that Planck resolved by developing a theory of quantized states and quanta https://en.wikipedia.org/wiki/Ultraviolet_catastrophe.

Quantization is real. But I've never seen any phenomenon that can only be explained in terms of the full concept of a particle (which is a decidedly nonrigorous one in any case), and while the concept of a quantized wave is certainly counterintuitive, I'd argue it's simpler and more consistent than wave-particle duality.
