Simple observation shows some being occupying some space on some land on some planet. These are all physically real. If the being is a man and the space is then labeled a country on planet Earth, what transpires that requires the man to acknowledge the label, an abstract concept, and all that it entails, such as the authorities of those who have declared the label, its boundaries, and so on? I don't think it is any mix of any particular ideology, politics, ethics, philosophy, or morality that behooves the individual to acknowledge the country. I think it is the physical power to enforce the mix of ideology, politics, ethics, philosophy, or morality that defines a country that requires the individual to acknowledge it.
In other words, is a country's existence defined by the degree of violence its definers can summon to impose upon a denier of the existence of their country concept, and in the absence of sufficient violence, the individual can resume recognizing only the physical realities of being some being occupying some space on some land on some planet?
For tangible reference, if indigenous native Americans or Australians had possessed superior weapons, could Europeans have established the U.S.A, Canada, and Australia with inferior weapons presenting only some mix of ideology, politics, ethics, philosophy, or morality to persuade the indigenous people to submit to the declaration of a country?
