Nor when we give licences and large vans/trucks to people who want to crash them. It's about managing risk and historically most hijackings have been by passengers and there is no significant loss to securing it with passenger jets having two pilots (ie, if one passes out), its win-win.

Meanwhile the vast majority of what the TSA and a significant-enough chunk of what security agencies do is pure theater, in exchange for a significant headaches and loss of privacy/dignity/time/etc of citizens who fund and technically support such organizations - and everyone else visiting the country as it deters plenty of tourism and business travel.

Screening of pilots for various issues, mental and performance wise, has increased substantially since 9/11 as well.

what are you saying here? you would argue that cabin should not be secure, so as to guard against a hypothetical attacker who completes professional pilot certification and gets a job as a copilot for the sake of (hopefully) overcoming the captain 1 versus 1 and brings down the plane?

because that seems ridiculous

Hence having two or three of them up there. They can't all be suicidal...
