I never thought I’d see Caledonian affirm the existence of angels,
And you never will, barring some truly remarkable evidence.
You seem to have misunderstood. Having an invisible, intangible, etc. etc. dragon in your garage IS having no dragon in your garage. Having quantum collapses IS having Many Worlds… unless and until you can demonstrate that the two are different in some way. And it cannot simply be noting that you use different phrases to refer to them, because that’s not a property of the phenomena, just how you choose to talk about them.
When it can be shown that they have different, operational implications, then they will be distinguishable. Until that time, they aren’t. Arguing over which of two indistinguishable things is correct is fundamentally wrong—they both are.
