Nonsense. Normal people don't pick up heavy things off the ground? Really?
If something is too heavy for me to lift, I will get help. I can’t see going to the gym in hopes that the skill acquired from deadlifting a barbell will transfer to that box that’s been in the middle of my living room floor for six months. Should I practice walking around with the barbell? Every time I’ve ever picked up something heavy off the floor, I’ve had to carry it somewhere. The best thing I can say for the deadlift is that it’s not as bad as the back squat.
