I don't have a problem with people creating items, per se, but I think there should be some serious GM control in the process. There should also be a drastic diminishing return for selling magic items.
Too many times I've received magic item proposals that are totally legal but also totally ridiculous. You can place restrictions on a magic item until it is only usable by the character it is made for. This reduces the cost so dramatically that the power of the item is way beyond the scope of the current character level.
Well, actually, DMG item creation rule does not guarantee that players can use all the guidelines freely without permission of their DM. That section is guideline, not a solid hard rule meant to be used without guidance of DMs. So basically nothing is "totally legal but also totally ridiculous". If a DM thought it to be ridiculous, the DM should simply disallow it to make or raise the cost.
Personally, I completely disallow that cost reduction rule. It is simply broken. If we allow it, when a creator is not intending to sell that item, there is no reason to not making an item usable only by him, or by certain party member.
