"You are desperately trying to dilute the role of government. I challenge you to list down to me examples which can be handled in an efficient manner (for the purpose of promoting general welfare) that are within the scope of individuals. Please also list down examples that are beyond the scope of individuals and has to be handled by a government. I will wait for the two lists. OK"
Individuals not only efficiently handle huge, welfare works, but also efficiently organize colossal welfare projects.
It is they, who, if they feel the necessity for a large scale organization (call it governmental or whatever), take the necessary steps to form it.
In my imagination, it is a scenario, where, the proverbial lamb and the lion drink together from the same water hole.
Everyone would have evolved to that degree. That will require the least government control.
And it will be a World government, not requiring any Defense arrangements in order to kill human beings.
At the most, there will be a battery of state-of -the-art rockets (like the historic Sultan's Battery at Kasargode, South India), standing guard against any perceived Alien attack.
