I suspect that gouging-without-countermeasures causes much more damage than anti-gouging, though.

  Specifically in case of tennis balls, I would argue that having them expensive is still better than not having them at all - tennis players need to practise.

    How long do they last? Can we possibly change these arbitrary sport regulations making the balls last 100x as much?
