Gonna put this out there just in case you're actually not pretending to be retarded.
Full automation still means that people are in control of those machines, and unless you can make machines that don't break you can't people will still have to repair them.
On top of that the people who control the automation have full power over every human being under it. And do you think a people that knows no struggle will stay peaceful? No, they have a standard of living and will want more, even in an unrealistic enviroment. When people are handed everything they learn nothing and become sacks of meat on a couch with no value. Through this you create a people made up of trash and nothing. Through this people will be dissatisfied and rebel.
No matter what you do you will still have people who crave conflict, both positive and negitive, and communism is unrealistic because of this.
Without some sort of struggle, there is no passion. No passion means nothing made.
You want to eliminate one thing that got us to the point where you can freely express your desire for an intentionally flawed system, and that's conflict.
A system of government that ignores or tries to steamroll over human nature is destined to fail, no matter what.
And when you fail, people die.
The only way you'll get your paradise is if you make advances in technology through science, not social theory bullshit.
Quality of life is what you should aim for, because your endless desire for control over other human beings does not get results. But you're a sack of shit with no skills, so you attached yourself to a movement that seeks to make change, that anybody can join.
But you can't change a fucking thing. And you can kick and scream all you like, but bring harm to people and you'll be put down.
