[Harry Potter] What is the point of chasers in quidditch?

If the game is only ended when the Golden Snitch is caught by the seeker, why have a point system with quaffles and keepers and chasers?

Bear in mind the games we see at Hogwarts are unusually short, rarely lasting more than an hour or so. Professional Quidditch matches can last for days at a time, because they generally have a snitch with a more powerful enchantment on it.

In a multi-day game of Quidditch, you can end up with hundreds of points on either side, so 150 is really not so big of a deal.
