Granted. You have ultimate power, but also ultimate responsibility. Have fun micro-managing literally every detail in the cosmos so that things don't immediately go tits-up.
I wish I had money to order chinese food for lunch.
Granted, You find a large bag of money! However, you are arrested before you can spend any of it, on the slight problem that you stole it. I wish for more cats!
Granted. You are soon captured by the government however, on the premises that you are some kind of spy or madman. I wish for the Midas Touch, but for diamonds, not gold.
