Not really. Companies can have dedicated office spaces that have a limited number of offices/cubicles dedicated to specific employees. Dedicate area to reserved and unreserved conference rooms/enclaves. And have desk or other space for drop-in employees. Also cafeterias, etc. Where I work, there's already a lot of space reserved for other than dedicated offices/desks.

Companies can absolutely have their own spaces that aren't primarily oriented around the idea of everyone having their own dedicated desk.
