I honestly start thinking that the idea "everything should be symmetric in some way..." is completely wrong, and an example of wishful thinking "...because it would be cool if it did". Even if nature is in some way balanced on a scale large enough, it's extremely unlikely for us not to be in some local pocket. Most likely we're a part of some bigger structure that has certain properties, and this affects our perception of the laws of physics.

Which would also be the reason we have the laws of physics we do in general.
Anything seemingly ad hoc in our universal (from our vantage) viewpoint is potentially explainable as a pocket among all other possible distributions/combinations of relations.
