If teflon didn't decay it would be fine as it doesn't pose a health risk, its basically inert. Its the manufacturing chemicals and degradants (PFAS/PFOA) that are the problem and represent persistent contamination.

Magnesium is protected by a passive oxide layer and isn't particularly water reactive (unlike sodium and potassium which will react with water more readily). You can toss a chunk of magnesium and water and nothing happens.
