With no scarcity there can be no profit

  Profit is derived from scarcity. If goods and services were infinite, no one would be able to make a profit and all businesses and jobs would collapse. Opportunity is exploiting some apparent advantage. But if there was an infinite number of flat screens, diamond rings, and gold bullion etc. just buy picking them up at the beach. Then why need dept stores or sales people, and advertising or any number of jobs and business institutions?
