That's why you have to judge players based on the era that they played in. No question that if Ruth had the advanced strength and conditioning that every player takes advantage of in MLB today he would have been even more of a beast. By the same token if Bonds plays in the 1920's he's probably still a 20 home run guy but nowhere near the 73 he hit or 700+ he hit for his career. And yeah- I know he would have been playing with Cool Papa Bell in the Negro Leagues but my point remains.
