Plastics have many substitution options outside of the narrow range where it's the best choice.
I'd be more concerned about how gas is feedstock for pharma, and fertiliser.

Would you elaborate on what you mean by this? I don't follow.
Peak oil is not really just about untapped stocks, it's about the economics of supply and consumption. We won't "run out" of oil, it will stop being viable to produce it when gasoline ceases to be so economically important.
The feedstock uses of ethylene and lng are justified by the underlying consumption of petrol, diesel and heavy oils. It's profit from waste. If the gasoline isn't used the refineries shut down. If the entire cycle has to convert to fertiliser the economics of fertiliser change, and prices change.
