Because people who say "Do this, I want to give you money" often turn out to:
a. Not really have money to give.
b. Not really want to give money.
And frankly, "getting money" is probably low on Katherine's list right now. She has a product roadmap that she's executing on and doesn't want to be pulled away from. The money stuff will come later if she charts the right course.
It's counterintuitive at first, but as an entrepreneur, once you get burned a few times creating a feature or changing course due to a request from "someone who wants to give you money", you start learning to tune out the folks who demand stuff with that kind of domineering urgency. I've found this very difficult on my end and have people on my team help spot when to tune people out so I can get better at it.
