I've actually enjoyed reading this discussion but wanted to point out a few things. First, people do take PEDs to increase their "daily productivity". ADHD drugs are now the drug of choice for HS, college, graduate level students, and professionals looking to get to the top.
Second, I don't know if you ever raced, IH8, but if you had, your opinion of PEDs may change (assuming you raced clean). This is where your opinion of sport differs from that of an athlete (meant in the classical sense); that cycling is not a sport but a form of entertainment. If cycling or any other athletic endeavor is merely entertainment, then I too would have no problem with the use of PEDs, just as I have no problem with movie stars taking drugs and getting surgery (some of which have fatal complications) to make them look hot on the big screen. Part of the job. Remember, you may watch cycling for the entertainment value, but the cyclist races for the athletic value (at least at the amateur level). Even if all spectators were to disappear, people will continue to engage in athletics.
My objection is that I still think athletics have their own intrinisic value. There's a reason Plato, when discussing the merits of professions, placed the athlete near the top of the list and actors/entertainers on the bottom.
Simply put, the use of PED's by one forces the use of PED's by all if it is a fair competition.
