Where is the "otherwise authorized"?


In the regulation you referred to.



Newps suggested that the pilot accept an approach clearance, and then
simply break it off and land without executing it, if I understand him
correctly.


Newps is wrong.



An intriguing idea, to be sure, but presumably the approach controller
only authorized the procedure which he cleared the pilot to execute,
and which the pilot then circumvented.

Seems like a possible violation to me.


It is, see my response to Newps.
