Wild take, copying matters. If you have a great idea, and no capital and I copy you and have more capital (money, social), I can deploy my capital to crush you in the market. This very idea that ideas don't matter is hogwash, you can say that idea alone is not enough, but it matters. This is why big companies sometimes get sued by the govt, they copy smaller companies ideas, add it into their already established product for free and stifle growth for the world.
