You wish that people could live in peace and harmony and that followed the “concept” of the Commune.

If the economic science itself doesn’t account for what is the goal here. It shows a lot of hubris to talk about “goals” for society at large. It can work for a small group of people with a shared view and unchallenged leadership (like a small corporation or a family clan), but try living like that in anything larger than a small village and you will quickly see that the system is not sustainable. The Commune of Paris is only one of many examples.
