What's utopian is painting a picture of the minutia of what communist society will look like, that's what you're doing now and what every Marxist repudiates
No state, no money, sure, because that's seen as a resolution of the contradictions in class society and therefore a logical conclusion
No law enforcement? Factories and shops? You've made up your own image of communism in your mind and have decided that's what everybody else thinks, and use your own utopia to discredit scientific socialists
Why would someone living under communism have to educate themselves on communist ideals? People living under capitalism don't educate themselves on capitalist ideals, they take it completely for granted because that's the status quo
