It is abundant, so we're not going to "run out", but it may reach a point where it's impractical to recover. As the second most abundant element, a lot of it is found diffuse in the interstellar medium and in stars. It's not useful to us there. Right now, it's easily and cheaply available by extracting it from certain deposits of natural gas. We should price it based on long-term need and long-term availability, which doesn't include the helium found in distant stars.
