No, anyone who can come into an office should come into the office. We have very flexible work hours with some core days/hours where everyone's schedules should overlap. FWIW, most people I've worked with prefer in-office to WFH unless they have extenuating circumstances like a long commute. Having a good, quiet office with respectful coworkers and management makes for a great environment.

The organization will never be perfect and stay perfect, but as long as you pay attention to it when hiring and designing teams then it can be close.
