I think that's an oversimplification of the argument being made. For people early in their careers, face time on site can be invaluable. They get to learn from people who get things done, and emulate them (or not). On-site, they learn from both positive and negative examples. This is simply less effective through meetings only. The counterpoint also ignores human behavior. The person getting promoted is likely to be the person who shows up every day and visibly contributes when compared head-to-head against an equivalently performing employee WFH. First time people managers will likely be expected to manage people where their boss can keep an eye on them before entrusting them with remote teams. This could create a career choke point. the advantages you mention are real, but WFH is poor career advice unless you can compete on price with low-cost foreign workers who are just as remote as the person I am paying a US salary to
