I'm not sure what you mean.  Economists earning graduate degrees from top colleges commonly study early during matriculation that absent any govt regulation, supply and demand determine availability (concerning supply) and pricing (concerning demand).  Otherwise, please excuse my use of a metaphor.  Arising concerns over oligarchy and monopoly usher in the proposition of govt regulation...to wit:  "no supply-demand pricing of medical services."  This principle of pricing has nothing to do with scientific fact.
