Air also has inelastic demand. It is just that it is too cheap (that doesn't mean that the producers make a good profit) to produce an enormous quantity of it (even though fresh food is perishable), so much, that even the US and the EU agree on agricultural quotas and/or increasing tariffs over a certain quota of imported quantity.

For Switzerland & Germany the way the incentives work are different than in the US, but the market for compulsory health insurance is very strictly regulated and the cost distribution for healthcare is distributed across public and private entities (particularly for very expensive treatments, rare diseases, treatments involving machines of great complexity/cost [like for proton therapy]).
