One of the reasons certain things 'cost' so much to make is because when they are made they are worth so much. Without copyright these thing surely wouldn't make as much money as they now do, so to take your example of a movie, actors would therefore not be paid as much and so on down the line.

So I think the question is should so much money be made from some of these things?

Should for example actors and sports players be insanely rich while teachers and other public servants make so little?
