Far too many rules and exceptions to be found in the regulations.
Yup, I disagree...these exceptions allow far more latitude on the part of the PIC, which quite frankly I would approve of.
We don't need the tower/approach to tell the pilot...do not land, the field is closed.
Unless, of course the runway might be blocked for whatever reason.
FAA...far more practical, IMO.
In many ways....

Costs, for example.
