Not to mention, every person responds differently to doping protocols.
What if you're a C rider who becomes an A+ rider when doped? And you race against a B+ rider who becomes an A minus rider when doped. Still not an even playing field.
This is effectively what lance did. He had record levels of hematocrit naturally, and an extremely high vo2. It meant he had a magnified sensitivity to doping protocols that the other riders didn't. So his doping advantage actually increased his relative abilities even -higher- than his also-doped competitors.
Not to mention kids coming into the sport. Would be a massive mountain to climb to go from a prodigy 16 year old against doped pros.
Everything-goes sounds fun in theory but in practice it'd just kill the athletes (and the sport, by extension)
Notably, this is probably part of why the Olympics doesn't have bodybuilding, powerlifting, or strongman on the program, as sports need to have a WADA-approved antidoping program to qualify.
Also, the Olympics itself from the 50s to the 80s basically was what you're asking for. This is the time between when synthetic steroids were first widely available and when tests for them became possible. In the meantime, with no way to catch anyone, it was anything goes. I wouldn't say that led to pretty outcomes. Records that stood for 40 years, sure, but eastern bloc nations with mandatory athletics camps were injecting 12 year-old girls with testosterone and telling them it was vitamins. At a reasonable dose, most performance enhancing drugs are fairly safe for men but virtually none of them are safe for women because of the masculinizing effects. The changes to a female body are permanent.
100 die of the drugs during childhood
700 suffer the rest of their shortened lives from consequential medical issues
perhaps its easier to just throw the 'failed' 990 into a meat grinder to ensure there is no controversy later
but sure, its fun to watch the 10 athletes at the peak of their game!
