Nowhere, but FAR 91.113(b) does say "vigilance shall be maintained by each
person operating an aircraft so as to see and avoid other aircraft." Why do
you assume that a pilot might not be doing what is required by the FARs,
while assuming that he will adhere to a non-required "standard" practice?

Then what in the hell do we need dumb ass controllers
for????????????????????????????????

Uh oh. I think you've reached the salient point.

The bottom line is that we *don't* need ATC for most GA operations.
In fact, as I've stated before, imposing Class D "controlled" airspace
actually reduces safety in many cases.

ATC is needed at Class B airports. ATC is handy to have at most Class
C airports, but only during peak operational hours. (Which is why, for
instance, Cedar Rapids Class C is only part-time.)

Class D is there because (at some point) your Senator wanted a control
tower in his district.
