And the conversion rate is good at quantifying how much actual influence a person has. Which may be less than they think.
How much influence a typical YouTuber with 10k subscribers have? Very little, actually - they can affect audience's thinking in a limited domain, or get them to buy some stuff to a limited degree. All restricted to how much a cohort of volunteers cares about what their entertainers tell them.
Contrast that with a person wielding a $100. They can literally get someone to do almost anything for them for a couple of hours. Or, in general, they can exchange it for $100 worth of goods and services provided by an industrial civilization. That's what hard influence looks like.
