You seem to assume that if they hadn't have been cheating in the '70s, they would have won anyway (which may or may not be true), but so what? Since they did cheat, and they did win, aren't they just as guilty as the '90s cheats who won? In fact, in some ways, isn't it worse - at least Riis had a reason to cheat, if Mercx would have won anyway, why did he need to boost his performance with peds?
By the way, I don't feel strongly about this, just examining the logic.
To me, it's a bit more complicated than your post suggests: in the absence of studies where the same riders go from clean to using different PEDs and improvement are quantified, I choose to believe LeMond, and see the facts that are available (such as him being outgunned in '91 as the defending champ). Or times on climbs among other things (Johan Bruyneel besting Hinault's or LeMond's times on Alpe d'Huez). According to LeMond, EPO was a revolution. You couldn't win clean anymore. So it seems like you could win clean until then, right?
The use of banned substances, for some riders in the pre-EPO era, was to help recover from injury (i.e. Hinault's cortisone shots). Now, if using a banned substance helps you improve your performance the following day (better recovery), it's doping. I agree with you.
Although some pre-EPO performances (such as Joop's mutant climb mentioned on another contribution) were not normal, it seems like you couldn't safely use the most efficient PEDs over the course of a three-week race without taking huge risks. The world of PEDs was 'artisanal' at best, tantamount to playing russian roulette at worst. Tales of use of crazy stuff such as drugs developed for horse racing abound. Even alcohol was used as a PED (no Floyd, I'm talking about Jean Robic). When it comes to steroids, doses were minuscule if we judge by how much the bodybuilders of the day were using (i.e. Arnold '67-'80) vs. what they do today.
There's little doubt that had EPO been available then, its use would have been widespread. By using the existing data as corroborating evidence and testimonies from former DS and riders, many conclude that PEDs before the EPO era were generating little more than marginal gains. A clean rider could win.
