I'd say people naturally tend to crave independence once they have grown strong and mature enough. You know, the same way children eventually leave their parents to claim full control of their own lives, and follow their own path under their own rules alone ?

In geopolitics, it's called the right to self-determination and is a sacred political right in democratic societies. Even America itself was born this way, by declaring secession from the United Kindoms after the colony had sufficiently developped.

Yes, the Republic offers great advantages, but goods and services are inherently exportable, if only to make them available to such a gigantic and far-spanning population. So they can have what they love without bending the knee to a greater system they no longer need.

I'm not trying to downplay your Republican version, but it just seems highly improbable for matured communities to obey their "parent" for life without some implacable un-democratic coercion, which in turn casts a dictatorial shadow on a supposedly republican system.

I can totally see humanity being united into a Star Trek - like Federation of independent communities (each their own "wo/man" while sticking together out of political wisdom), but as much as I hate to admit it, a Cassius-like approach seems the only credible way to permanently merge them into a single entity.
