Urbit may not have much to do with any specific government but it absolutely has a lot to do with governance and society in general. If you do not believe there are fundamental flaws in not only the reality of the internet / online services but the structure of the system in which they grew, Urbit is not worthwhile for you. If you do believe there are flaws, but you disagree about what the flaws are and how to solve then, Urbit may even be counterproductive.

Here are the first words of the intro on Urbit's home page: https://urbit.org/understanding-urbit/

> We think the internet can’t be saved. The way things are going, MEGACORP will always control our apps and services because we can no longer run them ourselves.

> The only way out of this mess is with a completely new platform that’s owned and controlled by its users.

A little later: https://urbit.org/understanding-urbit/interface/

> One way to imagine Urbit is as the Western answer to WeChat: a seamless, multi-purpose, vastly extensible social network, but without the surveillance.

And from their "Beliefs and Principles" page: https://urbit.org/blog/beliefs-and-principles/

> The ability of the engineering community to govern itself through republican forms is not an abstract theory; it's a proven fact.

> Urbit should never fall under any kind of central control. All transitions in galaxy ownership should divide positions, not unite them. Galaxy and star ownership should also be separated. It is harmful for a single entity to hold both galaxies and stars.

> Urbit has zero tolerance for abuse, nor does it facilitate censorship. Urbit will do everything possible to help you block content you don't want to see. It does nothing to help you block content you don't want others to see.

If you are happy with the role of governments and corporations in Western society and the resulting online landscape, it's not clear you need Urbit. It's fine, but it's overhead. If you're happy with the role of governments and corporations in China, for instance, if you like WeChat and how it works and why it works, Urbit is actively useless to you.

And you can oppose China (or even Western governments) and find Urbit useless too: if you believe the problem is with the holders of power but not the very concept that people can hold that much power, or you are skeptical of mechanisms to prevent people from holding that much power - perhaps because you fear covert power and collusion, or because you fear that tools that inhibit the accumulation of power are more likely to harm the powerless than the somewhat-powerful - Urbit doesn't present you with solutions that help you.

I think it's entirely fair to say that beliefs about governments are absolutely a part of why Urbit was created and why it continues to get development interest from people besides the creator.
