There is a cercomstances in which almost every modern service imaginable might be defined as a “necessity”. Whether any good or service is a “necessity” or not, it is not acceptable to have the Federal government steal from the mouth of the producer to provide that good or service.
That goes for cellphones, TV, stereos, as well as food, shelter.
Since I have no desire for the US to become a third world country, I equate food and shelter as necessities.
