You mistake the way western governments are structured with "governance of a society". The CCP is far more than the traditional there branches of the western democratic government.
Societies self-govern and create structures. Some of those structures are companies, some are government. Sometimes the government regulates companies, and sometimes companies regulate the government.
Edit: even in the US for example, ONLY the judiciary is concerned with defending individual liberties. If that's all that's necessary then we wouldn't need elections, just a military and that's that.
You seem to heavily discount the amount of work it takes to become post-scarcity - most societies in the world fail to achieve this, even for simple things like cell phones in 2021.
That the CCP is far more is clear indication that it is too much.
(In the US) The judiciary is very obviously not the only branch concerned with protecting individual liberties. Law makers pass laws with the intent to do so and the President can command the military to do so if necessary.
The world is on track to completely eliminate starvation and abject poverty in a few years, maybe a decade or two.
Projected life span and quality of life is at an all time high on average, and crime is overall down which is another indicator of plenty rather than lack. It is utopian minded idealism that everyone should have everything they want (including cell phones) and the world should become 'post-scarcity' (whatever that means). I have found utopian minded idealists to be the least experienced with regards work.
The rest is fluff that should be put down with violence if necessary.
