I think the OP is missing something. The market transaction is between the gift giver, and whomever she purchased it from. The use value i.e. as a gift, is fully realized as soon as the gift is given. The only way value would be lost is, if for some reason the gift couldn’t be delivered, and the giver could not realize either a use value or an exchange value from it.
The difference between the use value as a gift and the use value as a product that the recipient would have been willing to buy is what is being proposed as destruction of value. Alternatively, one could argue for the giftgivingness of a gift as a creator of value, just as vanity or status-consciousness is - none of which should bother homo economicus, of course
