Its goal is not to do something effective to solve the problem addressed, but to pretend to do something to solve that problem. Pretty much like airport security. If they were to do something really effective to address the problems, in the case that occupies us here accessing many sites would become so difficult and inconvenient that most people would just stop doing so, with the concomitant revenue loss for those sites. In the airport security case passenger throughput would grind down to a treacle, which would come in with lots of negative knock-on effects, including many people just foregoing flying.
What to do then? Pretend that you are doing something so you cannot be blamed for doing nothing, while at the same time you keep revenue flowing.
Yes, humans are the stupidest animal on the planet.
