Could those mechanics be altered by an arbitrary change in universal constants making any order impossible? Sure, that is concievable, but there would be no one in that universe to ask questions.
As I mentioned in my previous post, I'm not sure that the fine-tuning "problem" is really a problem that needs or could be solved. However, I also don't find the anthropic principle compelling either.

A pretty sizeable chunk of science is investigating and understanding phenomena that human life depends on.
Now it's true that why this constant is 4.3 instead of 4.2 is a different kind of question to "How does water dissolve so many things?", say. It's a Why question vs a How question, for a start.
But for me, I don't see why that makes the anthropic principle "work" or be a satisfying answer.
