Ok, so then would be correct to say that the communist utopia is a sort of singularity (consider y=1/x, where x=0). It can never be achieved, but the goal should be to get as close to it as possible. We will never achieve total post scarcity. However, we can achieve post scarcity for things like food, shelter, clothing, healthcare, education, then probably internet access, smartphones, video games and so on.
We can never eliminate institutions of authority, but we can reduce their presence as much as possible. For example, we can never eliminate the police force, as there still would be some sociopaths who we would need protection from. However, as society would progress, crime would drop such that we would require smaller and smaller police forces.
So in conclusion, am I right in considering the communist utopia as a singularity?
