It's a common misconception that people pay for value. They pay for perceived value, which isn't the same thing. What might be "useful" or "valuable" often has no value to others. What has value to others might in actuality be worthless on its own merit, but has perceived value to them. This explains the whole "influencer" ecosystem, and how some startups became quick Unicorns while others languished trying to raise even seed funding. There's very little correlation between what one thinks has value and what others value.
