The thing with helium though is that it’s already privatized. The geologic formations that trap helium from uranium and thorium decay are the exact formations that trap fossil fuels, particularly natural gas. Whether it’s worth it to capture that helium is purely market driven by private interests. Most of it is just off gassed into space instead of separated. All that government production has amounted to is making helium cheap enough to put in balloons and use on wasteful cryo applications with no recovery mechanism like it was subsidized, making separating it from natural gas uneconomical. Increasing the price would decrease the monumental waste we already do.

Well, the half lives of the stuff that produces helium are generally above 500 million years so we’ll still be making more of it for a very long time, but the reserves we’ve found trapped in geologic formations certainly are limited. /s
