i kind of understand your point. the problem i see is that it might make you think you're doing something amazing while not receiving and adapting to customer feedback.

so in the end it's very linkely to build something that people don't care about or don't need.

this would be perfectly fine if you'd use your own money. but your investors invest in you because they want their money back plus profits.

so, you're right. now you're fine. but when the money or money or both are gone you get into trouble if there's no revenue and profit.

good luck!
