I don't think patreon is a good metric since there a low number of people pay for content early or exlusives, meaning the cost is distributed among less people. A video on youtube will cost less and has less value since it's available to more people.
Sometimes we pay a lot more: https://graphtreon.com/patreon-stats
> The true value of the video is likely much lower.
The true value of the video varies a lot. Some are demonstrably very highly valued: https://graphtreon.com/top-patreon-creators
