I think that Jonas thinks that his community isn't a really hard society to live in because he already lives there. He's already used to all his rules. For people that live in this society including me must think that it's a hard world to live in since it has too many rules and not enough freedom like the one we're used to having. People being the same creates Unity because you work the same
And act the same, because everybody's following the same rules. They're all the same.
