trisher I think your'e failing to grasp it too. In what parallel universe do you think a child, who's parents are being protected by a 'minder', if he was with his parents wouldn't also be protected by default. Or do you think in the event of being faced with a gunman, say, they'd grab H&M and leave Archie?
Let me put it another way, Archie, who is not a prince and cannot be one until C is King, does not attract his own, personal security team. He can and did benefit from the team provided to his parents. Now he still does, it's just that they are paying for the team. If they had wanted extra, they would have had to pay, just like Andrew does for his daughters. It's really not that hard to understand.
