I have always felt that most doping rules in sports are pointless and stupid. (Pro athletes in some sports abuse their bodies so badly that the added risk from steroid use disappears in the noise.) But this is not the way I would go about changing the rules.

Suppose that boxing were controlled by a single governing body (there are at least three) and that they decided to do away with the weight classes and let any fighter challenge any other. It's easy to predict what would happen: only the heavyweights could compete. The rest would be driven out of the sport. This is what will happen to any athletic sport that doesn't segregate the sexes, or lets (biological) men compete as women. The women will quit. I don't want that to happen, and I don't think most people do.
