I think the point of his question was the golf isn't all THAT physical. (Plus he even wrote it into the first sentence that he was speaking more on relative terms from their respective tees) Luke Donald or Justin Leonard or Corey Pavin can still have a lot of success on tour as short hitters. None of the stuff that those guys do to be successful is really stuff that would be considered in the "power" category.
Nobody is ever going to suggest that women would be able to compete with men on a level playing field, but there really is no reason (other than lack of participation) that should keep them from being as good from their relative distances. (Unless Ben Wright was correct in his assessment ;))
The second part is not true. How many women can put a sufficient back spin to cause the ball to roll back or even stop as soon as it hits the green? Most, if not all, women golfers rely on their balls to run after hitting the green. So they can't attack any pins that are tucked behind a bunker or other hazards, whereas even Luke, Justin and Corey can put enough spin on their ball to have it "drop and stop" or "drop and roll back".
"Power" doesn't mean exclusively distance.
