I think you are thinking of the inconsiderate morons who take their 65 liter "backpacking through europe" pack onboard.
Unfortunately, there's also slightly oblivious onebaggers who choose to carry a MLC which is too large for them to carry. It's about finding the right bag for the travel scenario and making a good game plan to reduce hassle. That person with a neck pillow, flip flops, water bottle, and speaker dangling off a massive wide turtle shell down the confines of an aisle, obliviously staring at their phone checking their seat number and twisting about to check rows? That person who is happily "one bagging" and will decide to stay in the aisle while pulling out a good quarter of their bag for a 2 hour flight, then throwing it in the bin sideways with the sole handle in the most inconvenient place to unload it?
Stowing efficiently does take a little practice in the confines of economy, surrounded by others. Japanese travelers do this extremely well, not only because checked luggage is the norm, but also because of how many people take public transit regularly and have been taught to queue and stow efficiently. Most have a game plan to shift their bag into the least disruptive carry mode before entering the plane, know where they are sitting, and step into the row to store instead of holding up the aisle. They're also good at disembarking. I've observed Japanese travelers who started stowing their things and tidying like folding the blanket neatly when pilot announced we're going to land soon. Nothing was left out in a seat for row mates to trip on and no last minute fumbles to stow items.
