You're making the same mistake that Yuval Noah Harari made in his book Sapiens... the belief that capitalism REQUIRES you to make every single decision in your life based on monetary profit motives.
This is obviously incorrect.
Do I need to charge my kids money before feeding them dinner in order to be in adherence with capitalism? Obviously not. Does capitalism allow me to be charitable with my neighbor? Obviously yes. Can I decide to buy something local even though it costs more than a similar item on Amazon or Walmart? Yes I can, and that doesn't mean I am violating capitalism.
Capitalism IS free/voluntary exchange and engagement.
People can voluntarily join a commune under capitalism!!
What makes it "communism" — the way 99.9% of human use the word — is when there's a centralized government pointing guns at people's heads, forcing them to behave in certain ways.
Your post describes people voluntarily engaging with one another. You are describing free markets / free exchange / capitalism.
Additionally, these are nothing more than meaningless feel-good nonsense:
> "in favor of a decentralized, stateless society where resources and goods are communally owned and managed."
> "manage their own affairs, making decisions through direct democracy and consensus."
> "exchanging goods and services based on need rather than profit"
> "work together for the common good"
> "operate on principles of mutual aid and shared resources"
These all mean NOTHING until applied to a specific situation. And then anyone with the tiniest bit of mental maturity would understand that SOMEONE is going to decided what different people's "needs" are... SOMEONE is going to decide what "consensus" means... SOMEONE is going to decide what "the common good means" etc etc
So, yes, communism IS coercion... and nothing you said in this incoherent post above demonstrates otherwise.
