I am awfully bored of these “everything is simple, open offices are uniformly awful, everybody should be remote” arguments. Yes - this works for some people, in some workplaces. In other cases, it doesn’t work. I’m fine with my open office space, and I prefer working from an office - which is a bike ride away and better equipped than I am.
How about instead we accept that there are almost certainly trade-offs involved in these areas, and that maybe building an office space that works for everyone is important? Provide open office space for those who thrive in that environment. Make sure there are private areas for those who don’t. Establish a culture that supports remote workers, and encourages good behaviour in shared areas. That, if anything, is simpler.
