Like others pointed out defederation, but to add the important bit for normies (don’t mean derogatory at all) is that it is not meant to be a less complicated or more efficient experience, it is meant to have more (or actual) freedom and democracy.

Much like with gov politics, you have to be active to some degree or a few people can control everything.

So yes, when defederation needs to happen or communities moved (for much of that additional tools will streamline the processes in the future I’m sure), it’s a bit messy, but it doesn’t rob you or feed the megacorps pushing the society into more inequality.

As you established that is not true, however you can add some of that carbon from some body and add it to the iron from the blood of 400 other human bodies so you can forge one nice sword.

always had this question as a kid

And then went, draw it out, and asked.
I applaud that (and the art), good for you.

(And the good people already provided answers.)
