I like to think that Skyrim, and probably the past TES games, are not only open worlds when it comes to exploration and game quests, but also when building your character along the game. I mean, I think they allow you intentionally to make an early fortune with the enchanting iron daggers method, or overpowering your armor and weapons with the known method. It's just the freedom to do so if you wish, and I think it's nice of them to let the players who are not that interested in challenge to have their way.
I say this because, while everywhere these kind of methods to get a lot of power and resources are called exploits, I think lots of them are not getting past the standard mechanics of the game.
I think there are glitches and there are options, and options are never flaws in an open world game.
