The "launch fast, fail fast way(launch an MVP and iterate it)" is to optimize for the company and investor, not the customer.
Investor wanna see the MVP and traction because they want to de-risk a "deal". Most of the VCs care more about who is you lead investor than the potential upside of the product. As a founder, you need to de-risk your future by truly validate your product hypothesis.
The Lean approach will lead you to very incremental solutions or even make you run around in circles achieving nothing. It lowers the cost of failure (downside), but also the potential impact of success (upside). This approach determines your mindset as a product designer and destroys your potential product/business upside upfront.
