Disagree with the majority of this post. Picking up and putting down is a common movement, but not in a manner that's similar to deadlifts and certainly not at a weight where regular, fairly taxing deadlifting would make a difference in the average person's quality of life. The examples you use in your post are either specialized or infrequent. I'm trying to think of some circumstances in which the average person I know could use the alleged benefits of regular deadlifting during the course of a typical day and the only examples I can think of are my wife and the other mothers of toddlers we know. I say mothers specifically, as the fathers rarely complain about the weight of the kids after holding them for long stretches. As for rarely using bench pressing movements, gotta disagree there, too. There's a large glass security door in my office building that you have to go through to get to the bay of elevators that stops at our floor. It's a very heavy door and you constantly see people struggling with it. Whenever I am away from the gym (and bench pressing) for an extended period, I really notice the weight of that door. There's a restaurant called "bread and butter" around the corner where I eat lunch pretty frequently, It has the same door issue. So for me, on a daily basis, the bench press provides a more practical benefit than the deadlift. Obviously, everyone's lifestyle is different, but that's actually the point I'm trying to drive home. (Not that presses are better)
You are being wildly bias here. Pushing open a door has very little to do with the pressing movement done in a bench. When you open a door you lean into it and use your legs. Take note the next time you are opening that door. If you are pushing it with your arms with hands starting at your chest and extending past the half way point you are opening the door wrong.
And you don't have to exactly duplicate a DL or RDL for it to aid in any movement where you pick up a weight. DL strengthens all the major muscles used when picking things up: back, legs, hams, grip.
And holding a baby is more of an isometric position not aided much by DL but constantly picking up and putting down a baby is.
But like I said, you don't need Deads to be a bber and to look good but, as far as functional ability irl, nothing beats it. But you don't like Deads. I get it. It's a hard movement that real drains you. You are more concerned about pretty muscles. That still puts you ahead of the game than the majority of the fatsos out there. And AAA will change your tire for you.
