I disagree in principle. "Pacing" would imply everyone maintaining a
fixed distance between them and going at the same speed. That doesn't
happen often in "real" aviation. I cruise toward the imaginary VOR at
75 MPH. United 405 may be at 550 MPH (granted I am at 500 feet and they
are at 34,500 feet)...but my friend behind me may be at 500 feet and 110
MPH, therefore I better be checkin' six.

Determine the exact position of each aircraft? Nope, I don't have a
transponder and unless ATC is using primary radar, they don't even know
I exist at that VOR.

Precise traffic control increases safety to the extent that you can control
and determine the exact position of all aircraft at the same time, but it also
diminishes safety to the extent that you _cannot_ do these things.
