TSA=Tied Shoes, Annoying?

Why, why, why do we still have to take off our shoes to go through airport security? As if it's not sufficiently humiliating to endure a manual pat-down because your sweater, is, I guess, hooded? (True story, and I was not offered any explanation as to why a completely non-charming woman felt around my armpits while holding up a long line of travelers behind me.) I have also seen men clutching their pants in desperation as their belt buckles travel through the x-ray machine, while also trying to maneuver a laptop back into a bag and perhaps wrangle a small child through as well. And, what with the similarly unnecessary liquid restriction, we are also asked to put our various creams and balms, some of which have, shall we say, personal applications, on display for all to see (checked bags, I think not, with handling fees and lost luggage issues what they are these days). The shoe removal is especially irksome in summer months, when no shoes often means no socks, and therefore hordes of perfect strangers are forced to hop around barefoot on a cold tile floor, without a lap pool or coconut cocktail in sight. All because one single traveler, once, many years ago, attempted to board a plane with a device in his shoe? Was the shoe in question a flip-flop? Give me a break!
