We're probably just fighting over semantics. What you call opportunity sounds more like a proven idea versus your typical idea that needs proving. Take the many instances when we say something like: "I have an idea: we could try selling blah to blah people." Is that an idea or a possible opportunity? I'd argue it is both. Or "I have an idea: let's sell to blah people because I know they'd love this". Is that an idea or an opportunity? I'd argue it is both. No where in the definition of an idea does it specfically exclude anything related to market opportunity.
