Abstract
We critically analyze the rationale of arguments from finetuning and naturalness in particle physics and cosmology. Some other numerological coincidences are also discussed.

None of what you say contradicts that HEP Theory is in a crisis. That word was thrown around before the LHC confirmed the Standard Model, it's become more acute since. The crisis is that the foundational ideas about how to make progress in physics: Elegance, beauty, naturalness…
On the contrary. She suggests adhering to it. The notion of whether a theory is elegant or beautiful is exogenous to the question if it describes nature, hence should be cut by the razor. In technical terms, there is no need for a prior on theory space…
