The article was a study in stupidity, but this question has been raised probably since the beginning of time. I don't really see the point of the question. Rich or not, stupid or not, at the end of the day, they're all humans. Most rescue organizations are based on the moral compunction to save another human's life. Being rich and stupid doesn't remove the human part from the equation, and outlawing their rescue unless they pay a fine is basically saying that they are less human because they are rich and stupid.
My other thought was - if we did enact fines for rescues caused by idiotic actions, who would get to decide what's idiotic? I can think of a lot of people off the top of my head that think that any time a person goes up in a GA plane, they are taking idiotic risks; or when a person goes motorcycling, or diving, or driving a sports car, or going to a track night, or going camping...and that's just a short list. And who gets to decide whether someone is rich or not? To some people, my life would be the height of luxury. To others, barely above the poverty line. Whether someone is rich or not is also very subjective.
I personally think that a good-sized donation to the organization that rescued you would be in good taste, but making it a requirement opens quite a few cans of worms that I would not want to see opened.
