Wish and the Ring of Spell Storing

Why mention spells of "level 8 or lower" if everyone is going to be casting every spell at level 8, because thats what will happen if your interpretation is how it works?  

Because not necessarily you might want to upcast a spell. You can if you want, you probably should if yoou are in battle, but you don't have to. It's your wish.

Also, Simulacrum can't be upcast :)

Any spell can be upcast. It's just that some don't derive any benefits from doing so.
