So all of the examples your provided are understandable but not exactly the negatives I was looking for to push me away from using PP over win/loss as the draft order. I was looking for PP work arounds that would still allow someone to gain an advantage compared to the win/loss method of setting the draft order. I want to prohibit a team gaining an advantage (higher draft pick) by purposely losing a game that could affect playoff matchups/standings/etc. (depleting your team in a legit effort to improve for the future is not an issue for me as long as you can submit a complete starting lineup and the trades are trying to better your team for the future).
I actually think PP is a fine alternative to reverse W-L. There are pros and cons. But yes, the biggest feather in its cap is that even covert, above the board efforts by a team to limit their PP won't give them any incentive to enter a bad lineup from their available roster options, which essentially hand out uncontested wins that affect the playoff race. That can be reason enough to go in the PP direction.
My position is more contesting the notion that it's a full proof way to prevent a bad team from successfully tanking for the 1.1, stealing it out from under a team that's worse / more deserving. I know that's not your position, but I've heard it presented from others (including some in my league) as, "here's the solution that will completely solve tanking"
It is certainly more difficult in some leagues than others based on roster size, number of keepers, and how easy it is to get a trade done. In my league of keep 19 of 25, effective tactics that aren't over the top are going to be a long play over multiple weeks. There aren't assurances of a successful low score for a single week if core players go off. However, over 3-5 weeks, a single QB is probably going to have less PP than a best-ball tandem of 2 QBs, if all QBs are more or less the same tier.
Along those lines, a rebuilding team in my league has 3 quality QBs (including two of the younger assets). I think he wants to hold on to the youth until he's sure he has his QB of the future. However, the best ball score of 3 starting QBs will probably boost his PP by quite a bit over teams that are carrying two comparables. Should he feel pressure to trade one away for the purpose of limiting his PP? If he gets decent seasons from all three with stretches of good play, he could still be a pretty bad team in terms of W-L and overall roster talent, that now has no chance at the 1.1 due to the PP he's getting from QB.
