It all depends on what you care about. People dying waiting for an MRI doesn't end society as we know it, but someone will probably be sad about it

If you're worried you can keep your own helium reserve? Then if there is an emergency and it turns out that you don't need an MRI you can sell the helium to whoever does and feel really good about your foresight.

I'm not seeing any need for a strategic reserve here. There aren't any strategic issues. It is a bit far-fetched that a helium shock will even lead to the end of MRIs.
