I'm not discounting moonshot business ideas. I'm saying there's a bunch of capable people out there that may not have any idea what exactly to build. And I'm saying people like that could benefit from active discussion on ideas of what to build, and people that already have ideas of what to build would benefit from discussing their startup idea & business plan with others prior to diving in head first.

I'm basically saying mix wisdom of the crowd with the startup-idea generation process.
