I understand what you're saying, despite not necessarily agreeing with everything you are saying.
It's just really odd to say:
"X produces the best model we have"
But also say:
"X is an unlikely solution".
If it produces the best model we have, it's the most likely solution at this time. That doesn't guarantee it will ultimately be the correct solution, sure.
Totally fair. But we're in that weird spot where we've been trying to find a concrete example of dark matter (testable hypothesis that would apply) and so far we're not coming up all that hot.
So I guess "unlikely" is probably too strong even in my opinion. I just think it hints that we have a structural problem in the house, and continuing to add wall paper is probably not going to fix the issue, we need a shift in understanding somewhere else.
