It's useful to ask who your business is going to be because it's a concrete acknowledgement that you are not your business. Once you do that you can decide which parts of who you are should be applied to solving the problem you're going to solve, and what contributions you'll need from others to complete who you want your business to be, whether they're contractors, co-founders, employees, advisors, or whomever.
Your business will also have a personality, but that's only small piece of the picture, just as a person's personality is only a piece of who they are. A person has skills, abilities, a point of view, values, etc., just like your business. And the way your customers will relate and interact with you as the provider of a product or service, is more similar to how they would relate to a person than anything else. So I think the lens is useful.
