> unnecessary concepts of private ownership and hierarchy of command

Claiming that these things are “unnecessary concepts” is a significantly more extreme position than you make it seem. What are the alternatives that actually work?

see the entire field of anarchism for instance, Francis Ford Coppola even has a new movie coming out that draws directly from the works of David Graeber and Wengrow who have written on your kind of anarchy101 level question. I recommend trying wengrow and graeber’s Dawn of Everything or their academic papers. Understood it’s extreme to you. The writing’s there if you have the want to see it.

Cool theorizing; but just one example of a current society that has flourished using no private ownership, please?

No current societies are anarchist no. See ya

So you have zero evidence (aka much stronger true believer) of what you say working and you want to restructure the world based on fairy tales spun by the likes of David Graeber?

See ya.

Yep, this would never happen in a system without private ownership.

As such a system would never give rise to Twitter in the first place (hence problem solved).

Or such a system will forever reside in the Platonic ideal universe forever avoiding any real-world flaws or criticism.

Btw you replied to a wrong comment but good on you for looking up my post history ;)

Not at all, you don’t understand the anarchist position if you say that

Twitter in a system without private ownership: you stay up late in your attic with a flashlight, writing your tweets on a smuggled typewriter. The next day you hand them over to a high-ranking colleague at work who has access to the copier, whom (you hope) you can trust with your life.

Come now, thats unfair and unrealistic. Likely, you get thrown in a gulag for not possessing the license to tweet.
