Managers do want people in the office to physically lock them: if you are a giant in a certain place most works for you or have to migrate elsewhere and moving homes scare many, it's not easy, family members might have issues moving their jobs together, eventual kids might suffer loosing friends and change schools and so on. People in the office means people more tied to their employers, more keen to accept not-so-nice things at work, not-so-nice changes and so on.

While remote workers can change employers potentially just changing some login screens, witch makes them less keen to accept bad work conditions or bag changes.
