I wonder if this will evolve to the "inspectors" writing their own
"search warrants"? Like the Patriot Act did to Federal agencies...

The Patriot Act did no such thing. It expanded the use of "administrative
subpoenas" from the handful of places already authorized by law (financial
institutions, storage shed rentals, etc.) to any commercial facility.

Here's why the change was sought:

On the morning of 9/11, FBI agents fanned out in Boston hoping to get the
hotel check-out records of guests that had left earlier that morning. The
idea was that by matching these guests to the airplane manifests they might
uncover a clue leading to suspects still in the air.

In every case, the hotels refused, citing "privacy" concerns. There is, of
course, no LEGAL privacy right to a commercial transaction; the hotels were
merely following their own policies. The hotels could have been compelled
via a warrant or grand jury subpoena, but those would have taken several
hours to perfect.

The change provided by the Patriot Act revision now allows the FBI to flush
out these records forthwith.
