You haven't been around long enough to realize this isn't the first time they've made changes to the k system. And as soon as it is no longer profitable in the current format, they'll change it again. Years back when you gave someone k it wasn't taken out of your k total. Out of fear that one day the k system will be flooded with too much karma they changed that rule. But if that was the thinking, why then come up with a lottery that does exactly what they were trying to avoid in the past? It's simple, $$$. EF is a business, nobody will deny that. And believe me when I tell you if they find a way to make it more profitable, maybe one that drastically changes the way things are now, consider it done.
