Not JUST water but air too. Magnesium does not like oxygen. Probably other gases in the atmosphere as well.

If you don't seal it out completely, you will also start to see stress cracks in it at some point.

I know that the original Halibrands used on the race Cobras at low temperatures will actually become porous and won't hold air. They have to be heated to close the porosity. This I am told is due to the molecular structure of magnesium.

Magnesium will also burn if ignited with a good spark and some racing rules prohibit their use.

Lots of reasons to keep them completely sealed. It just wasn't happenstance that Campagnolo "coated" theirs.

Those offerings by Mr.Fiat are aluminum. Wonder how many, if any, he has sold at $1,500 each?
