Tragedy of the commons can happen no matter who you blame. It takes a government-level mandate to pay for cleanup.

I think it's simplest to force the consumer to pay.

I disagree. There are other things you can do with oil, and it doesn't pollute anything sitting in a tank. It's the energy production that matters.
