I literally don't see how any of that is different to my coworkers next to me being in meetings all day long and talking loudly, while I'm sitting there are trying to focus. At least at home I can ask my wife to take a kid for a walk because I need to focus for a bit. In the office I can't just tell everyone around me to shut up.
...or you can move yourself. With a big desktop setups perhaps not as much, but grab your laptop and head out someplace else. library? coffee shop? wherever. Working 'remote' I have options as to where to go to get privacy/focus. When I worked in office spaces, there were almost always some distractions that were hard to get away from (either logistically or socially).
Nearly everyone at my work has a proper big desktop workstation because we need the firepower that laptops don't really offer. Which rules out "just moving" and sitting somewhere else temporarily.
