Whats wrong with aluminium, like 80 of the earth’s surface is basically some aluminium oxid

Iirc there was something about aluminium in deodorant sprays a while ago that turned out to be not that bad, but what’s wrong with solid sheets of the stuff?

They come in glass or metal aswell, rice cookers always have an aluminium basket, the lid might be plastic and rubber but those parts are usually not mechanically strained. The microplastic argument seems weird here
