Expecting instant answers from others is the WFH equivalent to "I love being able to walk to my coworker's desk and ask them questions!" Sure, because being able to do that lets you off the hook for needing to break down large tasks into parallel chunks, plan phases of work in advance, juggle multiple plates for when you are blocked, etc. It's making your job easier at the expense of everyone else around you, by basically outsourcing part of your job.
WFH is a mindset shift.
