This is actually a very fine analogy…for utility magic. But when we’re talking about combat and healing magic and whatnot, I don’t really think it works. Even melee weapons wear down over time. Ranged weapons require ammunition. Yes, you may be using the same gun your entire career as a soldier, but you sure as hell aren’t recovering the same handful of bullets to be reused all the time. The same logic applies here - you may be using fireball to solve all your problems, but you can’t use the same wand or sulfur as ammunition FOREVER. At least, not without some serious upkeep to that wand.
