You don't understand because you don't know what "federal" means.
In fact, it has no meaning today, so I probably shouldn't have used it.
What we got was half federal, half national.
You basically have to read documents of the founding fathers, and get the meaning implied by the writing.
Anyway, a federal government is one that gets its power from those below. At any time, anyone below can remove their granted power.
Basically, it woulda worked out, in the war of northern aggression... the south wants to leave? Well, who are we to stop them?
I still don't understand why a federal government is necessary for that. Maybe it can work with any part being able to withdraw the power they granted, but why is the federal government necessary? Why can't it work with each part being independent?
Federal, as I have used it, does not mean national.
And federal is just one form of government that works as you indicated.
The United States of America was started as half federal, half national. After Lincoln, it is all national.
There are other types/forms of people getting together in groups. The better ones are voluntary. The best ones are those you can leave at any time.
Ah. So you're saying that all governments should be federal, in that power can be withdrawn at any time?
