Was John Galt evil, or at least a jerk, for not commercializing his motor?

In "Atlas Shrugged," John Galt went on strike when the world seemed only a little worse off than today politically in America. Things got really bad so fast because Galt dismantled everything. If, instead of going on strike, he had quit the Twentieth Century Motor Company and started the Galt Motor Company, things seem like they would have gone a very different way. By my reading, Galt's motor was pretty much a free energy miracle --- for the same price as a car engine a car could need no fuel and be nearly maintenance free. Electricity would be too cheap to meter and probably within a decade the Galt Motor Company would provide the engines for every plane, train, automobile, and power plant in America. The resulting economic boom from ultra-cheap energy would have probably improved conditions --- there'd be less calls for controls because everything would be going so swimmingly. Galt could have gone into the other countries and demanded they liberalize their economies if they wanted him to electrify their countries. His wealth and influence would let him meet with titans of industry and convince them of his morality. He could invest in Hollywood and make movies and TV shows that showed his views. He could have met Dagny and fallen in love with her, and I'm sure over months of dating she would have come around to realize that his morality was right. Her resistance was, after all, to the strike, not really the idea that we should be selfish. People seem to get more panicky and politicians more lusting after power when the economy is doing poorly. In huge booms things seem to get better. People who are well off don't cry out for a savior and accept whatever anyone tells them will make things better, because things are going pretty well. If Galt probably could have gotten rich, liberalized the economies of the world, married Dagny, and sparked a moral revolution all without dismantling civilization, shouldn't he have? If his motor really could save everyone (and it seems like it could have), he is at least kind of a jerk to not commercialize it -- and probably self-destructive too. So why go on strike at all?
