Interestingly, your definition of “everyday demand” is close to the concept of demand in economics, and your definition of “economic demand” is exactly the concept in economics of “quantity demanded” (the quantity coordinate of the point on the demand curve with a particular price coordinate.)
Very interesting. That means my first comment makes sense.
Because it would mean economic/everyday demand is very inelastic with respect to price. If I want world peace, a mansion in the hamptons, my own tropical island, that want will remain the same pretty much the same from day to day.
My short definitions would be
economic demand: the demand that exists at a particular price point.
everyday demand: a need or want, irrespective of price or availability
