Let me give you an example of what it would take to have a clean sport, from my perspective, you will likely find it absurd but it only hurts your current approach if you do.
1. Any couple that decides to have a child must also have their child monitored from conception to birth if they intend to allow that child to compete at any point in life, any children considered after the fact are barred from competition, we start early just so they don't pull in BS in utero.
2. From birth we monitor the child 24/7 throughout development to ensure the parents or any investors don't try to pull anything before they reach the competitive age. Also have to monitor the mother for obvious reasons.
3. Starting at the competitive age we carry over the monitoring, not a second goes by that isn't accounted for. If little johnny even tries to step on a tack that has been lined with a fraction of juicy juice, we will know about it and he will be flagged and barred from ever competing again.
4. We manage their foods, drinks, etc., so that no one is getting an external edge through any means, don't want any horsemeat getting through
5. We carry that level of monitoring over to the sport that they decide to compete in and it is maintained throughout the entirety of their career, 24/7 monitoring.
Who can we even trust not to breach rules with so much on the line? We don't know yet but everyone involved will be monitored 24/7 just to make sure they don't cheat, have to try something. How much does all of that even cost? I don't know, just print the money even if we end up with inflation rates that would make Venezuela blush.
But look, even with all of those precautions, any reasonable person would still conclude that we can only ensure, to the best of knowledge a ~99% likelihood, that's 99% not 100%, that we have prevented cheating (PEDs) from entering sports. Sounds absurd? Not really, not if you truly wish to prevent PED usage in sports, but that is what it will take for that sweet 99% that keeps us sleeping at night. With that in mind, do you see why I find it silly to dump money towards preventing PED usage with what we currently deal with, which is the opposite of what I have outlined as being necessary to achieve 99%? And you want to do it to secure a 10-30% likelihood of clean competitors?

Yeah forget about it, how about we just hire a cheaper USADA to keep the average moron thinking their sport is clean? Do they really even care? I wonder if there was this much bitching during Pride FC where no would flag when it was handled outside of the US, pretty sure people just enjoyed the spectacle.
