Granted. The Wishmaking Fairy assumes it's a new kind of virus that only kills people who wish. I wish that feeding cobwebs turned the cobwebs into dogs.
Long term is boring. Say there was a hypothetical long-term resource requiring module. You need to give it supplies, so logically, you put it in the closest deep space available. It's pretty tedious for a reward as trivial as science.
I don't think it's unrealistic. Sure, it may not meet the conditions observed in the Terrestrial (or something) system, but considering that planets are significantly more massive than they should be (and Minmus is probably made of salt), it's fine.
Granted. Since you are now capable of killing yourself, you are dead. You cannot come back to life without deciding to, and your soul left his magical god-sphere in your pockets. I wish for a cube of dirt.
Granted. Springs come forth and pound you down. They then hop onto every other living thing and mash them. Forever, just as you asked. I wish I had this beautiful duck :V
I put you backwards in time. Then I move forwards (and a bit sideways) in time to when Laythe vapourized. You are merely a fossil. Out of the blue comes a bluish sand-asteroid from Laythe, which is now my hill.
I ride a pet Legolas to your vault (and straight through stone). He fires an arrow at you, you know the rest. My pet legolas and isolated region of underground.
Point out the fact that helicopters cannot carry sufficient quantities of dirt or sulfuric acid. The dirt magically fwoops down, the helicopter bursts into flames and explodes (along with you) ironically, and out of the lake of sulfuric acid emerges a hill that's on fire. I use a fire fighting ram. The ram breathes on the fire and puts it out. My hill & enslaved/pet ram.
Granted. There are not 12 lakes of gatecamper so that giant battleships are the only things to survive. There are now 300 gatecampers, rough equivalent of what it takes to destroy half a battleship. This is equal to 12 lakes, the same as before (The wishmaking fairy is too rough in equivalents.) I wish for videogames to be pets.
