The common thing for players who come into the game is that it is a PvP game. And this is reinforced when they see someone go 10/6/4 and do a lot of damage. Its rare for them to run into, and get stomped by, that guy who has 180 minions at 20 mins. It just never clicks that you can get a lot of gold safely by farming.

The no defense thing is just people building to that they think their champion does and not to what they actually do. Take Nocturne, he's an assassin with all sorts of steroids, so I see him built with a Bloodthirster sometimes. However in reality Noct is a bruiser adept at sitting on a carry, and so is better off with an Aegis or frozen mallet.
