I agree with you that some streams should never see the power boat traffic, and in large part it's recreational power boating that makes many of our streams inhospitable. Two of my favorite rivers for overnighters might be considered marginal jet water, they also don't have outfitters, I justify the river Jon by trying very hard to avoid others boaters. I can usually put in mid afternoon, float and fish 5 or 6 miles only using the big motor to navigate an occasional tight spot, set up camp and never see another boater. In the morning I can often fish till mid afternoon without risk of disturbing anyone. On the run back up to the ramp I will occasionally see another water craft, but it's not too difficult to just kill the motor, maybe take a swim until they pass. My primary goal on all trips is avoid people regardless of jet or canoe.
