It doesn't alter your point...it amplifies it.
You are correct...remits can be restrictive. But the old saying, where there is will there is a way holds good....especially if you have a bit of clout.
The main point I was making was that taking an aggressive approach can often be doomed to failure from the outset, because then you can end up fighting the system and a bl**dy minded DO, Sqn Cdr, Flt Cdr or whatever.
