As was mentioned above, qualifying points is based off of the loser's score. Of course qualifying points only matter in ties of record, and if you never lose you're set, but the chances of that are low, so it's advised you rather have a high scoring match than a low one.

That, and I honestly think it is impossible for a robot to gather all 80 balls (I think it's almost impossible to even get 40 at one time). The other alliance simply won't let you; any robot that starts hoarding balls will be continuously rammed to be taken out of the game. If human players refuse to throw them in, there's nothing the other team can do, but remember those balls you're holding on to must be scored by the other team for you to get them, meaning they've already scored substantial points.

Lastly, hoarding balls would lead to a very boring game, and love excitement in FIRST.
