But many people do benefit greatly from hoarding or controlling the distribution of scarce information. If you make your living off slavery instead, then of course you can be generous with knowledge.
If you do not hoard your ideas, and neither do I, then we can both benefit from the ideas of the other. If I can access the ideas of a hundred other people at the cost of sharing my own ideas, then I profit; no matter how smart I am, a hundred other people working the same problem are going to be able to produce at least some ideas that I did not think of. (This is a benefit of free/open source software; it has been shown experimentally to work pretty well in the right circumstances).
