I think the real problem is that magic in D&D is so mundane that any problem can be “magicked away”, be it healing a wound, curing diseases or exploding an enemy. That makes some situations only really plausible when it’s explained as some stronger magic or “weird power” interfering with common magic.

It’s a magical fantasy setting, I get it, but magic being so common and consequence free makes it a deus ex of whatever flimsy explanation you can imagine. “Why do disabled people exist in typical D&D?” Cue that meme of the cartoon’s Dungeon Master “It’s magic, I ain’t gotta explain shit”.
