There's lots of helium in the solar system. You could harvest the atmosphere of Jupiter or Saturn for it. Obviously this has an energy cost, but s stated in the article energy is the only real resource that we use up. Everything else is renewable.
You would miss out on the "Crossposted from LessWrong. Click to view X comments." button at the bottom, but you can also add an identical comment manually.
If I did that, comments from EA will not show up on LW. But that is a good fallback. It seems that a crosspost has better functionality, and the 100 karma barrier seems a bit silly since I have 4500 karma on LW. But if that's the best thing that's possible, I will do that.
