There are two threads of copyright law:
∙ As protection of unique artistic expressions. There is a "spark of creativity" which is like any ordinary property.
∙ Unauthorized copying as bad faith business dealings. Creators can't create knowing that anyone can copy their work for free.
Both are part of the judicial understanding of copyright law, but at different times in history, one has been more prevalent than the other. Right now, the first is very ascendant.
