There is absolutely a distinction to be made between a foreigner and a citizen and their respective personal properties.
But that distinction is not relevant in this case. Case in point: your luggage.
Try using your status as a citizen to refuse your luggage to be inspected for contraband or taxable imports when returning to your home country from one with which it does not share a tax and customs union, and see how that goes.
We have the Visa application and interview process for that.

Could you pinpoint this distincrion?
What would I be allowed to carry through US border as a citizen but not as a foreigner? Guns? Cocaine? Illegal french cheese?
I think you are resting in fallse comfort that your possesions are more protected than those of unwashed foreign masses.
Border agents with unchecked discretionary power is also a slight against rule of law and I think warrants are a check on that power. Maybe they are more checked than I believe them to be or have less discretionary power than I believe them to have. I am open to the idea that I am wrong.
