> The TSA blog carries constant reports of weapons confiscated from people who forgot to remove them from carry-on bags. But the Homeland Security Red Teams in the 2015 test actively concealed forbidden items just as real criminals and terrorist would. The result was that "TSA agents failed 67 out of 70 tests, with Red Team members repeatedly able to get potential weapons through checkpoints."
> Two years later, a Red Team test at Minneapolis-St. Paul Airport achieved the same 95 percent failure rate to detect explosives, weapons, and illegal drugs. Repeat national tests in 2017 also went badly, "in the ballpark" of an 80 percent failure rate.
> In fact, the DHS Inspector General has long been a thorn in the TSA's side, compiling a still-growing collection of critical reports. In 2015, the TSA grew so upset with the criticism that it went so far as to classify some findings as "sensitive security information" in order to suppress distribution.
Conversely, there are ~40k-50k gun deaths annually in the US, and we do nothing, despite that being a much greater risk than an air transport terror attack.

Not all 'jobs' are of equal value to society
The TSA:
1. Expends a lot of money, and a lot of passenger time;
2. Without producing any benefits.
Thus, eliminating the TSA is pure upside.
Your question is irrelevant to the topic, because the TSA does not oversee what people bring on airplanes.
Also, fun fact, the TSA doesn't actually care about any of this. They're mostly concerned with large bombs and have lobbied to not have to chase after every pair of nail clippers but the flight attendants union has successfully counter lobbied to prevent this. They don't want to be stuck in giant metal tube trying to convince 200 irate people to pay $5 for a can of Fanta and to sign up for the latest credit card if anyone is armed with so much as a spork.
I have gone through the checkpoint with somebody who presented a photo id that was printed on an inkjet printer. Meanwhile, my holographic state-issued ID was subjected to four different tests.
The rules differ between major US airports. They differ between lines at the same airport. They differ between people in the same line at the same airport.
So it seems to me that some people already can bring whatever they want onto a plane. Which means that everything else is, in fact, theater.
Their other stats aren't much better. For the equivalent of $250m worth of effort, there are thousands of better uses of your time and money.
And today, right this second, you can bring high-powered un-extinguishable bombs onto a plane [0]. That comic is written in jest, but it really is trivial to kill a lot of people with common household devices and chemicals, including those allowed on planes. The world carrys on because most people are at least halfway decent, not because the TSA saves us.
