Your assertions are true as far as they go, but AMA insurance is then invalid, and most other insurers follow their lead. The AMA standards are the litmus test for insurabilty and represent 'good practice'
If the guy is rolling his own, he would understand enough to avoid this problem entirely. Your arguments while possible are unlikely in the extreme. The guy is at best using old assumptions with new gear, and at worst using ancient gear that is inadequate to the task, which is irresponsible. This isn't AM vs Sideband. Both were adequate to the task and neither induced a potentially dangerous failure in the other. They were merely annoying to each other. Given what we've been told, "evaluation of his receiver's bandwidth" isn't an option; he's already asserted that it's woefully inadequate and resisted attempts at a rational evaluation.
