Why Should There Be Copyright?

In my opinion copyright is a very good law that prevents people to abuse an artistic work such as a film or a book.
Having copyright, a writer or a film maker can be sure that his/her work will be presented to people without any changes in the quality or in the content. Nowadays all around the world, in many countries, this law is being obeyed and it can be a good help to the society of arts.
When some profiteers break this rule and copy someone's work illegally, they hurt the economical and mental situation of its owner. It also disappoints him/her a lot for doing the future works. But if everybody obeys this rule, the rights of the artistic work's owner will be reserved and every thing will be as it is predicted.
Another point that I can make is that this law will result in products with higher qualities and without any changes. So both the producers and the ones who buy them are satisfied with it.
Totally, it is very good to have this law in a country and check every body to obey it. So there will be more films, books, etc. and we can be sure of the products presented to us.
