One risk with value for value public payment models is that people may see N amount of zapped sats, and think, “that’s received enough compensation”. Their internal model of what something is/was worth is in equilibrium - yet the global utility/value is still higher.

It may translate into a deferred or more balanced zapping across content - however it’s likely to be a friction point too - where people internally question the above before contributing, and either zap other things or fewer things.
