There's a fundamental conflict between conceptual Utopia/Heaven and the law of supply and demand. All literary conceptions of a utopia rely on abundance of some good that is scarce in the author's time. Usually ignoring that its ubiquity makes it tend toward zero value. Here's my stab at Utopia, but it requires a belief that Knowledge is infinite: Utopia is a state of unhindered, continual learning at your own chosen…
That's a very specific view of Utopia that I suggest most regular folk would not agree with, moreover, it's a bit odds with metaphysical kind of utopias from antiquity.
Knowledge is ultimately still material, not necessarily enlightening. It's part of the dualist 'trap' that keeps us focused on what's right in front of our noses, 'playing some game' engaged in materiality. To me, bits of knowledge are just bits of lego blocks, tools for helping us describe experience.
Remember in Abrahamic terms were 'cast out of Eden/Heaven' literally for eating from the 'Tree of Knowledge of Good and Evil', i.e. the start of dualism and this never ending thirst for knowledge which distracts us from simply 'being'. You see this in eastern philosophies as well with 'attachment' to things, including knowledge.
But I do like your point about supply/demand perhaps (think of it especially in terms of social status, not material things especially) and constantly needing something, in your case, knowledge/learning. Neat thought.
