If someone actually works well remote and is responsive then they should be allowed to continue.
And in the cases where there is a delay I find that I still get the response quicker via slack than I would in person if I tried to find the person while they were at lunch in person and then had to go out of my way to try to find them again in the future, whereas the slack message allows for slightly async comms without me having to keep making requests which in my experience is more than adequate to get the job done.
Perhaps you need a lot of hand-holding day to day but everyone I work with does not.
The amount of times that I have had to go to the numerous different kitchen areas only to find out the employee left the building to get coffee or run an errand is just as high if not higher than someone being 'away' on Teams when I need them. Only at home I just set an alert for when they're back online instead of attempting a wild goose chase.
