You obviously have little experience in commodities trading in general, and gold futures in particular. Most contracts are merely rolled over to forward months, and replaced by new contracts. The apparent imbalance in physical gold available for delivery and the gold represented in the paper contracts is a theoretical imbalance, not a real one, and it is a non-event that has happened many times before now.
There will come a time at some point in the future, perhaps soon, perhaps not, when the imbalance you refer to will be a very real problem. But that time has not come yet. When it happens, the excess holders of long contracts will probably be paid off in fiat money.
