With imposed green targets and the reduction in oil demand the price will be low. Worthless is just relative. Non-oil based plastics etc. are already the norm. Crude oil isn't used that much to make plastics, gas is the normal source (LPG etc.) . Society aims to reduce oil consumption per person and one day it will be barely anything.
Let's hope so for an environment and dependency perspective. no one would be happier than me, but it is often called the black gold, I am sure there will always be a buyer in some legal back water
