I understand what you are saying. But your argument is true when you are bootstrapping a product. When you have already raised a pre-seed, whichbis what many companies are doing today. What have told a narrative to the investors to raise capital. When campaigns fail, it implies your narrative was incorrect and your understanding about the domain and market was wrong. Which might not be on entrepreneurs favour. When you are building a high growth startup these little lasting events can make or break. I have seen it happening with many companies.
