Yes. There is no such thing as quantifiable value to begin with, there is only "I want this more than that other thing so we can trade".

No one can ever send the full value in sats to a podcaster because they cannot know how much that value is -- if there is really such a thing as "value received".

Podcasting2.0 has this big philosophy behind it but it is really just "keysend donations", which is fine, donations are ok (although the keysend part is not a very well-thought protocol in my opinion).

But donations are not a solved issue. They are hard to compute. I think this is related to a point I tried to make some time ago: https://twitter.com/fiatjaf/status/1317581487563309059
