> Perhaps we could try to destroy those power structures without having a giant war

The power structure is what is putting out the satellites and datacenters that you hope will bring the Star Trek utopia. Not sure you can both destroy it and reap its fruit, or that the fruit is not poisoned by the immorality and antisociality of the current power structure anyway.

Also, in Starlink's case, if utopic United Earth becomes real, it will probably be cheaper to lay fiber and cell towers, so it's maybe just a bootstrap and not a final end state.
