So, I have a few things to say about this.
First of all, I think that diversity is good and a more decentralized form of organization is more likely to preserve diversity. Centralized authoritarian regimes like the modern People's Republic of China inherently trend towards genocidal policies because alternative modes of being threaten the state. If we can't even agree on basic values, why should we enforce an incredibly narrow set of values over a massive geographical landscape? Decentralized states aren't immune from this: the history of the United States being the pivotal example, but I think in general I think that flattening hierarchies and giving people more direct control inherently allows for more diversity in the modes of life.
Second, I reject moral relativism. My experience is obviously painted heavily as a westerner, but when I went to Egypt with AIESEC (international organization from every continent, I was the only American for most of it), what was most shocking to me was how similar everybody was. We currently live in a global culture, and if everyone on the planet can stand listening to Despacito for two months straight, we can probably assume some universals in the way we want to live our lives.
On a murkier philosophical level, I think we can make assumptions about universality based on us all basically having the same hardware. Even if you want obedience, discipline, and the pursuit of wealth, you probably don't want them for their own sake. They fill more fundamental needs: security, a sense of belonging, a sense of purpose, a sense of accomplishment, and so on. I think it's better if we work on solving these needs collaboratively rather than relying on systems that ultimately don't share human needs.
The third point is that there is some difficulty in reconciling the first two points. Often times, when people talk about preserving their local way of life they're actually talking about preserving an oppressive hierarchy that benefits specific powerful members of the community. A great example of this is the American Confederate South, where people will still argue that black people were happier as slaves and that the North enforced their values on the region or whatever. There are a lot of different cases of this happening, like when women in oppressive religious communities try to escape to a less oppressive culture or change the standards within their own community and it's again framed as the outside culture trying to destroy the values of that community. I'm hoping that these sorts of tensions get resolved as people become more integrated and connected, but ultimately the perfect shouldn't get in the way of the good and I think there are blatantly ways we can make things better for everyone especially when we work within our own communities and spheres of influence.
