#1 I'm not sure I understand the argument.

There's a huge problem with fields of science being subjugated by politicized pseudoscience.

It is also true that there has not been some fundamental innovation in theoretical physics for some decades in the face of puzzling observational findings about the nature of the universe at a grand scale.

But there's no reproducibility problem pertaining to quantum mechanics related physical phenomena.

QED for example is one of the most accurate theories known to us.

Also macroscopic phenomena that can only explained by quantum mechanics, like e.g. superconductivity, were discovered and explored by conducting reproducible experiments sometimes decades before the development of suitable quantum theories.

#2 The way my feeble mind understands the three body problem is that the problem is more about predictability than reproducibility.

Two celestial bodies interacting with one another can be predicted as to location at the instance they interact and how they interact using mathematics and quantum mechanics. A mathematical model can then be assembled.

But, when a third body is introduced, the predictability becomes much more difficult/complex and thus, the assembly of a mathematical model of the relative motions of the three bodies becomes extremely complex, so much so errors begin to creep in with the calculations.

The introduction of the third body is itself a problem.

YMMV
