We will never have a one world government, because concentrating power to one central point always leads to abuse of power, meaning tyranny, and the people of the world are just not going to submit to that, much less permanetly.
In answer to your caller, "how do we get to a war-free world?" - The answer is to continually decentralize everything that is possible to decentralize, to simply disable all the predatory pathways of the arrogant self-appointed "elites", who have been instigating every war in history for millennia, for their own filthy blood money profit.
Decentralization of all power structures and defunding the centralized banking systems that fund these tyrannical wars and power grabs, is the whole point of cryptocurrency isn't it?
Isn't the history of the abuse of humanity by people running the centralized money systems exactly why we're here today on Steemit in the cryptocurrency economy?
"Utopia" for the power hungry abusive elite, is hell for everyone else. Saying one global government is to "end wars" is a complete lie, since you'd have to make endless jackboot wars just to try to keep the rest of the world dominated and submitted to you.
And that's why we can't have, and refuse to have, a one world government.
