So you're saying, if Quantum Mechanics turns out to correctly describe larger and larger systems--in other words, unless we discover some new physics which makes QM break at a certain scale--then your pet interpretation will turn out to be true?
No, I'm saying that if Schrödinger's equation describes larger and larger systems that means that Quantum Mechanics is Schrödinger's equation rather than being Schrödinger's equation plus waveform collapse. Maybe you could try reading through the Interpretations of Quantum Mechanics Wikipedia page[1] to get a better sense of the issues being talked about here? Whether or not waveforms collapse at a certain scale is precisely the most important issue of disagreement here, and it actually is subject to experiment in theory. And experiment could probably even distinguish between the various families of waveform collapse too. Not that this will distinguish between all interpretations, but it would at least cut the possible number in half.
Remember, waveform collapse or "some new physics which makes QM break at a certain scale" was actually the assumption of the people who started quantum physics, and the default assumption of popular writing including the article we're discussing. It wasn't until much later that Everett proposed that it might be an unnecessary hypothesis like Maxwell's aether.
