The reason is because these high-profile clients need to protect their privacy and so make sure that those working for them especially their security agents, sign Non-Disclosure or Confidentiality agreements that require them not to speak of the things they hear or see about their clients.
Should they breach this agreement, they will be in a wealth of legal problems as well as suffer reputational loss. Sometimes though this does not seem to work and they still breach the agreement. It is a good deterrent either way.
When the writers of the Constitution were initially deciding what powers and responsibilities the executive branch—headed by the president—would have, they were heavily influenced by their experience with the British government under King George III. Having seen how the king and other European monarchs tended to abuse their powers, the designers of the Constitution wanted to place strict limits on the power that the president would have. At the same time, they wanted to give the president enough power to conduct foreign policy and to run the federal government efficiently without being hampered by the squabbling of legislators from individual states.
