Who would want to be left holding the bag with the expired "dollars" at the end of the period? I imagine they would trade at a substantial discount from the beginning, being dollars in name only.

I think you'd find most people would spend every penny before the funds expire. Anyone who doesn't is likely not too concerned about the funds expiring.
I don't think we can say for sure without a proper experiment (although if anyone can get their hands on EBT account spend data in aggregate, that would seem like a path to some signal, considering the financial condition of those who rely on those benefits).
I'm unsure how you get around folks who will launder this money into assets to counter the inflationary mechanism, unless you're means testing in some capacity, or you just don't care about the cohort who does this (which is a reasonable approach imho).
