(Socialists) On the value of stored goods in a capitalist society.

Debate regarding the LTV on this sub is ongoing. Many capitalists try to disprove the LTV by bringing up that wine increases in value over time even though the socially necessary labour time it took to produce it is fixed. Often times this is countered by saying that there is labour involved in the storage and aging of the wine, which gets embodied in the wine itself.

But this leads me to a question. If the labour involved in the storage of a wine gets embodied into it, wouldn’t this also be the case for any other good that is stored for any amount of time. For example, does a mattress that sits in a store’s inventory for moths increase in value as labour is used in its storage? If not, why?
