"Quantum theorists disagree with each other on things comparable to the existence of species. As in, some will say that there is such a thing as wave function collapse, others will say that this is nonsense and there's no such thing. They're not disagreeing on exactly when wave function occurs in some obscure corner case. No, they disagree on the existence of the concept itself."

This is an extremely uncharitable analogy. Physics is not a framework to guide your conceptual understanding of the world. It is human nature to try and conceptualize everything but there are limits to this and the interesting areas of physics operate beyond those limits. You can not conceptualize quantum interactions in a way that is meaningful because that process requires forcing our intuition (based on the macroscopic/classical world) into a space where it does not belong. This is why we create mathematical models to "describe" these types of systems and their interactions. To emphasize this, consider how illogical it is to try and "visualize" the fundamental building block that all visualizations are built with? There are visualizations of the corresponding mathematical models but they only provide insight into certain properties, they do not "show" you what a photon interaction looks like because the concept of physical visualization fundamentally doesn't make sense at the quantum level.
