- Taking into account the fact that the phrase " good"good reason" has a normative import, the reasoning could be reconstructed in this way :
(1) It is the case that X.
(2) If it is the case that X , then it is normal/ correctcorrect/ practicallypractically necessary that X.
(3) Then, it is normal/ correct correct/ practicallypractically necessary that X.
- Premise (2) seems to be analogous to the " is "is/ ought "ought" confusion.

"IsIs Ought
The is-ought fallacy occurs when the assumption is made that because things are a certain way, they should be that way. It can also consist of the assumption that because something is not now occurring, this means it should not occur. In effect, this fallacy asserts that the status quo should be maintained simply for its own sake. It seeks to make a value of a fact or to derive a moral imperative from the description of a state of affairs."
Note : by "practically necessary", I mean necessary in the order of practice (i.e. what one has to do or to comply with).
