if people are venting it away, it's because the people who would like to purchase it are not willing to pay the price. So the problem is that the uses of helium might not be commensurate with the cost of producing (or rather extracting) it. So therefore, the fix is to have the uses of helium pay more for it. Unfortunately, the payer of the uses of helium, such as for medical treatment recipients, do not want to pay more. As for balloons, the grade of purity is not sufficient for use in medicine, and thus is not realistically a problem (or the cost of refining it to higher purity is also costly).
