"Let it go" is exactly how we got into this mess.

If travelers hadn't "let it go" in the early days of airport WTMDs and x-ray for carry-on (before I was born), maybe we wouldn't be here today. Sure, nowadays most of us think basic carry-on screening for guns/large-knives/bombs is a good idea, but my limited understanding of this history is that it was quite controversial at the time. And lots of people raised the slippery slope concern which has clearly become true. If people had stood up for more individual protections (i.e., enforcing a clear distinction between administrative and criminal search, getting rid of "implied consent" and requiring explicit consent for each stage of the process, allowing pax to withdraw consent at any time), we might not be here.

If travelers hadn't "let it go" when TWA800 was used as an excuse for permanent ID checks, people wouldn't be so inclined to accept the papers-please behavior of airport ID checkers and Real ID. And the no-fly list which ensnares thousands of innocent travelers would just be a fantasy of some tyrannical bureaucrat . Yet another slippery slope come true.

If travelers hadn't "let it go" with the shoe carnival, we might never have had breast groping or total shoe carnival.

If travelers hadn't "let it go" when harmless carry-on items were banned after 9/11 (nail clippers, small scissors, pen knives), people wouldn't have been as tolerant of TSA's idiotic and ill-advised ban on an entire state of matter.

And after we were told to "take the train" if we didn't like TSA searches and ID checks, now we have ID checks and searches on Amtrak.

So sure, "let it go." How much do you want to bet that at least one of the following will come true in the USA?

1) At some point within 25 years, flying commercial airlines will require wearing only airport-provided clothes, and/or no personal carry-ons including purses or books will be allowed whatsoever.

2) At some point within 25 years, US citizens will be required to provide the government a detailed "purpose of travel" (i.e., "business" is not an acceptable answer) in order to fly domestically or in order to enter or even leave the country? The answer will be subject to review and denial will not be uncommon. Appealing denial, if even possible, will require a court case that could take months/years.

3) At some point within 25 years, ID checks against a blacklist and/or "administrative" searches will be tolerated for pretty much any travel activity other than walking, including entering an interstate highway, crossing internal border checkpoints (state lines, county lines?) and boarding a long-distance bus?

4) At some point within 25 years, you will have to formally apply/register for "pre-approval" from the government to engage in activities like going to college, buying a car, buying a house, or banking.

5) At some point within 25 years, a court ruling will state that the 4th amendment applies only to physical objects within one's (single-family) home and not in view of a window, because that is the only place where one has a "reasonable expectation of privacy." Rental apartments/houses and condos will not apply because one knows the landlord/management might get access, and therefore the resident doesn't have a "reasonable expectation of privacy." No electronic communication, including that going in and out of the home, will be considered private.
