The process of mining helium-3 won’t be cost efficient for a long time. It’s an overhyped material that requires sifting through kilometers of lunar regolith for grams of H3

It’s not the destination, but the journey.

Mining for He3 would require all kinds of new technology to be invented. And necessity is the mother of all inventions.

For sure and I don’t agree with the GP that the Lunar Gateway is useless. Even it just existing and people going to and from the moon will breed new systemic knowledge and inventions we otherwise wouldn’t have or need. Plus having a constant group of people living in orbit around another celestial body is just sexy in its own right.
