I think we are both arguing that some people narrow the scope of arguments to the point that they aren't useful to the original problem, merely more amenable to logic. Let's call this "not useful scoping".

I further argue that useful scoping (isolating the problem in a way that solving it provides a solution amenable to all those who proposed the problem) often /is/ the hard work, itself a product of much time and logic.

Far from proposing a useful course of action: I simply lament that we will often choose our scope to support simple logic, rather than use complex logic to improve the scope.

No surprise either: each life only has so many hours.
