You don’t. A tax is added on to every airline ticket I buy.

Airports make money from parking and many charge a surcharge to ride share companies.

You still have to go through the same scanners with TSA Precheck

If that’s your concern, why would you want TSA Precheck where you have to give the government your fingerprints and go through a background check?

And the airline already knows you are on the plane. They check ID when you check in.

Not getting blown out the sky is a pretty big benefit.

You know you don’t have to y if you don’t want to.

I'd rather just have practically none of it because it's largely a waste of money and time and a major inconvenience while providing practically little real security.

Tons of other countries have far more basic security at airports. They're not constantly having planes blown out of the sky. Airlines operated for decades before the formation of the TSA and millimeter wave scanners and taking off our shoes and stereoscopic face scans and yet they were not getting blown out of the sky.

Metal detectors were common since the 1970s. There were plenty of hijackings and a few bombings before then.

Also technology improved that the terrorist had.
