Who determines whether or not the actions of a state are in the best interests of society? That’s a great question, with a variety of answers depending on your preferred flavour of communism, anarchism, Marxism, etc. but the broad answer is that, well, we all do - as in, we, the working class.

Societies are necessarily structures composed of individuals, and therefore, individuals need to be involved in the decision making somewhere, it’s unavoidable.

There isn’t really anything you wrote which is uniquely applicable to a commune that isn’t also applicable to a transitional state. For example, what’s to stop such a state from determining that some innocent commune is involved in anti-communist, anti-worker’s rights activities and going wrecker, as you put it? Either by mistake, or for some malicious purpose, such as for the individual benefit of some individual in that structure?

You distrust individualists to exist outside of a state, but you trust them enough to be responsible with all of the instruments and powers of the state - that is quite strange to me indeed!

I tend to believe that, at the moment at least, humans are pretty selfish, ego-driven and tend towards making irrational choices. That’s why I believe that no-one should really be trusted with power over others that isn’t absolutely, 100% necessary for the functioning of society.

Also, just to clarify, there’s no such thing as a communist state - that’s a contradiction in terms. Communism, definitionally, is a classless, moneyless, stateless society - I’m guessing that you meant a transitional state, or a communist society, but a communist society couldn’t really “enforce” laws in the traditional top-down way that we think of those things.
