No amount of perks will make the game broken, unless you're playing on novice. If you want the best equipment, you'll have to make it yourself, whether through smithing, enchanting, or both. To do that you'll have to hunt down resources and items with the effects you want so you can disenchant them. Additionally, if you exploit alchemy, you can make some very awesome gear, though you'll still have to find some uncommon ingredients in large amounts. I'll admit that buying things becomes pointless after a while, but it's been that way since Morrowind as well.
Don't try to tell me Morrowind and Oblivion were more balanced, because they're not. And "the developers tried harder, the unbalanced parts are just unintentional and don't count" is no excuse, because how can you know? Why is the same thing laziness in Skyrim but unintentional omission form well-meaning developers in the older games?
Game breakedness is equally linked to natural progression in all the games, with unbalanced skills and the option to hunt down overpowered items. Alchemy's OP'd in every TES game it's in, while Enchanting, as a skill, was abysmally useless in Morrowind (Getting stuff enchanted by a professional was one of the only uses for huge amounts of money) but returned with a vengeance Skyrim. Destruction in Oblivion was gutted by the level scaling, but Alteration made Security superfluous.
