If you had confidence that those ideas are slam dunk, you would mortgage your house, take a loan, hire developers and have them build the idea. Then you would profit immensely and retire in Bali.

You're not doing that because you can't estimate the risk vs. profit potential of your own ideas.

Neither can anyone else and that's why there is no "eBay for ideas". It's a perfect example of market for lemons (https://en.wikipedia.org/wiki/The_Market_for_Lemons).

Consequently, there is no market for "daily 3 startup ideas".
