Lots of physicists don’t believe in many-worlds because they believe in some other theory or interpretation. Parsimony is often used to dismiss many-worlds; mainly because many-worlds doesn’t make any predictions so it’s difficult to refute on other grounds. That doesn’t make it true of course. If you have reason to believe that some other theory or interpretation is worth pursuing then you probably won’t spend much time refuting many-worlds. So parsimony will be the lazy way to dismiss many-worlds but not the reason you hold another view.
The reason most physicists working in the foundations of quantum mechanics don’t believe in many-worlds is because they take a different view of one or more of the assumptions you made (locality, hidden variables, the wave-function collapse, etc) and not because they don’t understand parsimony. They’re also in a far better position to judge those assumptions than you are (even by your own admissions). So even if I had no opinion on the subject I wouldn’t accept your argument. Your argument for many-worlds relies on claims of why physicists reject many-worlds that have no supporting evidence.
If I could level a general criticism about your essays it would be this: Your focus on other people’s modes of reasoning and biases makes you excessively prone to straw men arguments.
