Ah, gotcha, so when my neighbor’s house needs to be redone because he rewired it himself, I’m on the hook for that.

I already mentioned that a community could collectively decide to continue to enforce building codes.

Too bad I have to stand by and let a couple of transient drug addicts cook meth in the house next door again

There would be much less incentive to create drugs for profit in a world without money.

Not saying there wouldn't be drugs or addicts, but it's extremely likely the scale of the problem would be fairly drastically reduced, as many people turn to becoming drug addicts due to becoming homeless as a way to find some way to cope with the extreme stress and trauma of the situation. Without money, there would be no reason for China to continue to sell fentenyl and other drugs to the cartels to be shipped into the US, and the same for Cocaine from South America. That would leave only what could be reasonably produced at home, which would likely take the form of weed.

If, on the chance that someone did start producing meth in a community that has collectively agreed to not allow for that, they could potentially be ejected from the community.

Sure thing. That’s totally going to happen. ... it fall apart into vague handwaving about how everyone will be all helpful sunshine and smiles, which we know for a fact, people aren’t that at any level of their being.

It seems that you believe people are only motivated by money, status, or power. But we have examples of societies that were able to implement an Anarchist way of existence, such as Catalonia during the Spanish Civil War, which abolished money, the state, and was able to thrive as federated communities. George Orwell went there, and spoke of how excellent that mode of society was, to the point that he fought in the war and took a bullet in the neck for it.

Except it wouldn’t be their home. Someone else built it

They could have built it themselves, too.
