You’re missing the point. You don’t need to be the producer of the fuel to be in 100% control of the production and consumption when you have IP rights. Of course GAMI will offer to license their patent to anyone (who pays enough).
You’re confusing old economy ways of making money (e.g. by having a big expensive refinery that’s expensive to build and operate and acts as a nice barrier to entry) and the new economy (collecting licensing fees because you have exclusive rights).
