One thing that sort of bothers me a little when watching Minecraft videos is when someone breaks a block and leaves an item on the ground, and then they just never pick it up so it's left to despawn.
Though someone who's playing so much Minecraft that they're doing it as the focus of their channel probably has so much of everything stockpiled that one single fence item going wasted doesn't matter. :p

It's a different mindset. I could never do it, I had to build my stairs specifically so that I could reclaim every piece of dirt. Only block I could waste was netherrack, a block I had twenty double chests of and never used for anything other than scaffolding, and even then I still tried to reclaim as much as possible.
