Just as a purely intellectual exercise, what changes about this if we leave aside ideas of "owe," "deserve ," and "earn?"

There's not really an enforcement mechanism in FOSS like there is in capitalism world, it just comes down to what we want our part of the world to look like. So I think we'd think more clearly if we leave aside the ideas like "who owes who what." I think it's fun to imagine what sort of motivations and incentives there are if we put away the money ones.
