art and flexibility based on convenient needs – otherwise known as hypocrisy?

There seem to be a bunch of people that make objects which they term “art”. Once the “art” is used, they think it bestows added value, a numerical exchange value, which they seem happy to redeem.
On one hand the object becomes “special” because it might express some cultural value and meaning. On the other hand, such value and meaning added to said object, is very easily translate-able to the function of numerical exchange such as money..?
