I would prefer the Mossad model. Break the rules and they creep into your house in the middle of the night and kill you in your sleep.
I think it's sophistic to attribute the apparent lack of PEDs enforcement to a simple failure of "honesty." I also think the doping is unstoppable.
There is nothing the anti-PEDs forces can know, and no device which they can use, that the dopers can't also know, or buy, to include what methods and processes and devices Anti-PEDs will use to come after them. Plus, anti-PEDs works from a limited budget and must follow a set of publicly-published rules.
OTOH, nothing but their own imaginations limits what the dopers can do to advance their cause. And they are a for-profit concern that employs a positive feedback loop. The better they dope, the more money the can win and the more money they can reinvest in their doping program. Improve the doping, increase the winnings. Increase the winnings, improve the doping. Repeat ad nauseum.
As long as our society produces athletes who are willing to cheat to win, I do not think it possible for anti-doping to even narrow the gap, much less to stamp out doping.
Which at last brings me to the topic of this thread. What I think is going on in the large part is that most (if not all) sports governing bodies are aware that they are losing (or have lost) the battle against PEDs, and the advantages enjoyed by the dopers are unassailable. They have no hope ever to catch up.
Which leaves anti-doping but two options. They can admit the sport is irretrievably lost to doping, which likely either would destroy the sport, or so defame the sport's authority that it would be deposed. Either way, they're made redundant. Or they could enable the sport to continue to exist, but only behind a façade which they are obligated to erect of an ostensibly effective but utterly feckless anti-PEDs program.
And once they have sold out to the idea of fakery as means of preserving the sport, the challenge then becomes one of how to continue making best-faith efforts at PEDs enforcement in the face of the realisation they are merely tilting at windmills.
