[Elder Scrolls] I'm an incredibly rich merchant. What stops me from making a chainmail of enchanted rings and rule Nirn with an iron fist?

for starters, it would be a pretty shitty suit of armour.  
following that,you only get the magic effect from a few items at the same time.  

Finally, unless you are omnipotent, you can't be everywehere at the same time. If you ARE omnipotent, you clearly don't need a suit made of rings.

you need people to enforce your rule. you don't need a shitty suit of rings, but navies and armies to conquer those parts of Nirn who resist you. You need supplies and the logicstics to keep your forces supplied, and enough loyal men who can rule in your place when you are absent.

You can't conquer the world singlehandedly. Read a book.
