> They can search your physical property to see if there is evidence you plan to work in the US or are lying about your intentions for entering the US (all countries do this).
But doing this is useless. It only works once.
People who intend to work on a travel visa bring their work documents across the border, one of them gets caught, they object and take it to court. If the court says the search is allowed then it's henceforth public knowledge that it's allowed so people intending to do this stop physically carrying their documents across the border and instead transfer them over the internet.
Already it's common guidance for anyone to do that even if you're not breaking any laws, because it keeps them from rifling through your life and detaining you while they force you to explain whatever nonsense false positives they may find.
At which point the search is purely an inconvenience to innocent people and a trap for the unwary because anyone actually breaking the law can easily avoid physically transporting any incriminating documents across the border.
