According to Rekrunner, a positive test says nothing about whether an athlete doped in the past, so it would be unfair to take away previous medals or even doubt their previous performances.
But by the same logic, a positive test equally says nothing about whether an athlete will dope in the future, so punishing him with a ban is equally unfair. Maybe just suspend him for the few hours or so that the EPO remains in the system?
Not just according to me. I do not define logical constraints. But while you are at it, if the positive test is a false positive, it also says the wrong thing about the present.
The WADA Code is a "contract" where all parties must agree, as a condition before competing, that one consequence of a positive test is a sanction of a prescribed duration. This serves as a punishment and a deterrent, and not just as a means to directly prevent doped competition per se.
Sometimes your scenario plays out as you describe, like the case of Ajee Wilson, when the consequence of a no-fault violation was limited to annulling one performance, with no further sanctions beforewards or afterwards.
But it can still be a ticking bomb with further repercussions, as her next offense, whether intentional or not, will be considered a second offense.
