Trivially true if you define 'medical care' to include cosmetic procedures, which then gets you into case-by-case debates on whether this or that orthodontic or dermatological procedure is 'cosmetic' or required to live a normal life. Which then gets into debates about what pressures society places on people to have a certain look, and just how much social damage is done to someone who has a visible port wine stain, for example.
There's also a certain elasticity of demand for preventative care and palliative care as well. For example, flu shots and pseudoephedrine: Most of us here are not going to die of the flu, and most of us aren't around people who can die of the flu and cannot get vaccinated. Similarly, most of us here can get through a cold without taking symptomatic treatment for it. So there's a certain elasticity there, depending on the person.
But giving flu shots to everyone is likely a lot less expensive than losing even a single person to a serious flu infection. A similar case can be made regarding cheap pseudoephedrine versus losing some productivity to feeling like crap without the pills.
