I agree with you, and I want to call out a particular phrase you wrote as profoundly good advice:

"If you want to start a [$ALMOST_ANYTHING] company, talk to the people that'd profit off of it"

There's certainly more you need to know about starting and running any type of business, but finding the people who would potentially profit from a successful company is going on my shortlist of "Let's evaluate this idea" questions
