That would be true, except,
By giving away free daily points, we reduce the value of points as a whole, not just the value of the daily point. As Steve pointed out, if someone contributes in a big way to the site, like writing a featured story, they get 100 points. Or, the value of doing almost nothing over 100 days.
A featured comment, even less. By giving them away for nothing, all values eventually become meaningless.
Suppose we inflated everyone's points by an equal amount, say 1000. The proportional difference in points between Mizal and Myself would become quite a lot smaller. At the same time, our relative contribution would remain the same. That's the chief fault with the logic there.
