this would be a fantastic educational tool, it has the cutesyness and takeaway to be useful for children and teens. (also it's a basic incremental)
like Trobonkulous, i'd like you to try out some communist exploration (though i wouldn't say that communism is the only system without monetary incentives)
communism is not an ideology on it's own, like anarchism, it has to be complimented by another ideology to spell out a coherent ideology
like most of us, you're probably picturing the SU or CC as 'communism', however their ideologies are auth-left, which explains the centralization.
the counter to this critique is liber-left with less centralized figures and governments (not to say none) and more focus on collective consciousness (which could be good and bad).
