Why is it anyone's business what substances an athlete takes?

Medical reasons aside (and there's lots of debate on that issue), the issue relates to maintaining a level playing field among the participants in the sport. Bobby Bonds might be a better home runner than Hank Aaron or Babe Ruth, but if his performance was enhanced in a manner not available to the others, would his capabilities really be superior? The rules are there for several reasons, and that's one of them.

"the issue relates to maintaining a level playing field among the participants in the sport."\

First of all, you have to realize that professional sports is just "show biz", nothing more...

Olympic athletes are so highly engineered that it also has little to do with natural ability.

Your argument is bogus.
