im not sure erosion is inherently compelling as a threat.

i once tried to invent a new kind of money and even called my econnomics phd friend about it in like 2012 and the central part of it was that it ~did~ rot, you couldnt hoard

like a store of potatoes for a season, it wasnt if some is good more is better

there was such a thing as too much and didnt get thru them all and now your potatoes are rotten and moldy in the cellar
