I'm a toy inventor. I came with this idea - plastic building blocks for kids. I heard I can license this idea without getting a patent. My "coach" tells me I don't need a patent. He told me he was working hard and wanted me to succeed. If I license this to a manufacturer, NOBODY will copy this very simple plastic product - not matter how much MONEY it makes. Do YOU believe that? I don't believe that. What would stop them from copying me and getting a free ride?
