This is an interesting point, but the situation here is very different. For space launches there is a very little market, and if eg the Russians undercut you your potential customers will go to them and you're going to lose money. For electricity instead there is so much demand to satisfy that the inventor could make MUCH more money than he ever dreamed of just selling it in the Countries that would respect his patent.
