Something should be assigned a price ONLY if it is of value to your life.
What about all the things people buy to show off? These things add value to some people's lives because having them and being able to display them makes them feel better. They like to see the envy in other people's eyes, but these things are not vital to our lives. They don't make our lives better in any other way than by allowing us to feel better. Shouldn't these things have price?
IMO everything that has demand should have price.
People can be mistaken in holding an internal standard that their self-worth is dependent on the evaluation of others. Like I said, people can be mistaken or defrauded about values.
