We have so much gas where I live that there are places it’s just flared off and burned, because it’s less greenhouse emissions than it escaping unburned.
Helium deposits don't exist is the thing, the same structures in the Earth which trap methane gas also trap helium gas and some of them trap enough to make recovery economically viable.
Granted, the flare gas probably doesn't reach the prerequisite 100M-200M kelvin. I suspect high pressure is also required so the Helium stays close to the heat source.
