I fear unrestricted access would lead to over utilization by some people at the cost of less utilization by others. It could also lead to nontrivial psychological stress for people who can’t get a full understanding of the results. But I do think we need to strive for increased transparency from price lists to EHR interoperability to patient access to their own records.
Doctors are only scarce because they are members of a guild that uses monopoly power to restrict competition to prop up prices.
There is a high bar to becoming a physician because the consequences for error can be so incredibly high. I want there to be more physicians/access to medical care than ever but I don't think compromising on quality is the way to get there.
It's not like we haven't discovered higher temperature superconductors that could be used, even if we didn't have helium.
EDIT: You can permanently fill 100 of these[1] per year with the boil off of one shitty MRI. Is uses about 1kg of He, so one year of world helium production would be enough to make one MRI machine for every 200 people. We are not constrained by helium.

It's a limited resource similar to houses and carpenters. If it is permitted and there is funding, more can be built/trained.
