The proportion of physical delivery in futures trading is very small, generally only 1~3%, and most futures traders use hedging to close their positions.
Futures are different from stocks. To sell stocks, you must have stocks to sell, but futures can be sold without physical objects. It is wrong to say that commodity futures must correspond to physical objects one by one. One-to-one in futures is not real, and both long and short sides correspond to one-to-one short; Futures are speculative, so the proportion of final physical delivery will be small.
