What do you think a system that has managed to achieve “from each according to their abilities, to each according to their needs” would look like? Are you just imagining a Utopia and thinking it wouldn’t work? Marxists agree, imagining a Utopia and trying to build it is a failure in analysis of reality, hence why Marxism rejected Utopian model building. Read Socialism: Utopian and Scientific if you want to see what Marxists actually believe.
The main thing you are arguing is that your preconceived notion of Communism that you appear to have extrapolated from a single phrase doesn’t account for imperfect behavior, but you aren’t arguing against what Communists actually want, just what you think they want.
