” If you let people use any technique, then all athletes would have a choice, and wouldn’t be punished for their choice.” They have the choice, they do it all the time. As long as it does not harm others, and as a civilized society we want to avoid the bad example from people harming themselves. But, when fair play is involved. It takes that away. If you then said we will make it available to all players. It would always be a need of more and more. We know that eventually, players would be dropping dead at every game. Just so they can be the winner or try to be. Have to set a base line to avoid ego getting in the way of their own self distruction.. Genetic engineering is a whole other thing. Watch the movie Gattaga. At least for now, to alter someone’s genetic information to make them healthier, smarter and stronger. Would mean some would not be. And, you are (think you are) removing natural selection from the equation. No matter what you do. It will always be survival of the fittest. Today everyone (more then in the past) can stay in the game. (of life) When there was a time if you were not healthy enough you died. We all want to be the strongest or fool ourselves in believing it. Why are some harms allowable and some not. There is not enough time in the day to manage all of it. Especially when we tend to want what we want for the sake of having it. So we try to weed out the bigger issues but that allows for others to get under the fence. Funny thing about human nature. Power, especially absolute power corrupts absolutely. It is not about the best way to maximize our abilities. It does come, in drips. But some will not benefit from it. That is why people fight to prevent it. That prevention can be good. That is why we vote. That is why the hands of time go slowly.
