I disagree. There is no one specification for why a business exists. That's up to the creator/s.
I have customers so I can build. I do not build so I can have customers.
The enjoyment of creation is my motivation, making money comes after that for me. I'll choose poverty over not enjoying what I do but being better off financially (indeed, I've made that choice countless times).
Your approach reverses all of that. Which is fine, but it's not how everybody chooses to live.
