With the trend of orbital launches becoming cheaper, it might be that mining helium off-Tera will be our long term supply. Especially if the alternative is adjusting the amount of protons in an atom.

There are several challenges, not least of which is storage. We have considerable leakage in most of our current helium storage solutions on earth because it’s so light. Our national reserves are literally in underground caverns because it’s better than anything we can build. Space just means any containment system will need to work in a wider range of pressure/temperatures.
