I agree with all of this.

The vast majority of people aren’t good at being visionary, most aren’t technical, and many will give you a default culturally-aligned answer (eg positive to be nice and conflict-averse, or negative because they are tired of dealing with sales and bullshit, for example).

Therefore having some sort of MVP (even as said just a spreadsheet, or a storyboard) to help people understand what you’re even talking about and envision it in action, would be very useful.
