That's great to have ideas and monetize them, but you can't expect to apply property rights to them. That simply goes against natural law. Ideas by nature are intangible and reproducible at no loss to its originator. 
I believe in artists' rights to making a living but there are more practical, lucrative and natural law compliant ways to do so without copyright. Copyright law is a net loss to the economy.

what part needs explanation? 
the fact that one can indeed posses a concept (an idea basically) or the fact that (for example I am working close to) artists: designers, writers, musicians, all have trouble with copyright cause their work is usually used without royalties being paid.
