Hi Jim,

>>Are you saying potential receivers can overcome the effects of such interference? Or not be affected by it?<<

'Interference' does not take place in the air. It is easy to measure energy in the air, so laws are made about transmitting energy through the air - free-space laser power is limited because of eye safety concerns. Receivers are designed to receive certain signals and filter/adsorb others. The architect/designers agree to requirements (schedule/scope/staffing/recurring power consumption/etc...) and design accordingly. Increase the budget and you get a more useful design.

'receivers saturate' - the receiver's operation is based on the system's constraints, and the engineer's solution to those constraints. Any solution to the system constraints has limits in time/space/money/power dimensions.

It is not 'but at some point, there's nowhere to hop to, no clear channel, and no avoidable collision.
' - absent system time/space/money/power dimensions.

Radio astronomy equipment extracts signals from what antennas receive, and routinely combine receptions from distributed receivers. Their limits are closer to device physics than economic compromise. Their receivers do not saturate.
