> you can destroy money in the conventional banking system eg by burning paper money.
But that's an accident or intentional vandalism by a user of the system; it isn't built into the system itself.
> In both conventional banking and crypto, yes, there are situations of “sorry, you’re fucked, but like, you’re just supposed to know not to do that” (where “that” is send wires you’re not 100% sure of or guard your physical cash carefully).
In conventional banking the “sorry, you’re fucked” situations don't destroy the money banking is all about handling.
> you really seem to be drawing the abstraction boundaries poorly here.
My "abstraction boundary" (if I understand the term correctly?) is: A system that can have parts that do this -- destroy the very thing it's supposed to handle, "money" -- is a crap system. "Yeah, but you can burn cash!" (vandalism) or "Mistype an account number and the money is lost (to you)!" (not destructive) are not system critiques but whataboutism.
Currency-changing ATMs (do such things exist? If not, why not?) or vending machines like for petrol don't have built-in banknote shredders.
