No, if you hit a resource limit you’ve got exponentially increasing prices for the remainder which starts to make applications not even possible anymore. It’s not a shock in terms of months, but you could easily see MRI machines skyrocket in price over a few years as helium becomes inaccessible unless someone figures out a non-helium approach to MRIs.
That's the point, it's NOT a resource limits so there shouldn't be some exponential. As stated elsewhere, petroleum/natural gas companies are bleeding processable helium into the atmosphere, but only because there were government reserves that broke the economics. The can start capturing it.
