If you owned an oil ship, what stops you from getting paid $25 a barrel to fill your ship up with oil, sailing to international waters, dumping it all in the sea, then go right back to port and do it again and again getting paid $25 a barrel each time?
These are only the prices of the "futures contracts". i.e. oil that hasn't been produced yet, as far as I understand. Actual physical oil still has a price > 0. (Spot price)
