Actually, your point is still not well made. Although there are people out there who want to find a lucrative niche for themselves in whatever subject seems to be popular at the moment, there are also dedicated authors out there who would like to offer their books for free. However, we live in a world where the books must be carried on trucks, which require petrol, which costs money. So, the filthy lucre of monetary exchange still holds a very real place in our reality. The fact that Plato and Aristotle are dead does not place their books in a more worthy category than the many very good and worthy living authors who have something to offer, but must charge a reasonable price to cover their own cost of living. So, we will gladly continue to recommend books by what we consider to be worthy authors -- regardless of the fact that books do cost money. Perhaps when some communist dictator comes along and makes books free, you will be relieved. However, by that time books will more likely be outlawed.
