Assuming that the thing in his office is the actual space monolith, it's a huge safety hazard. Someone could get pulled to Maveth at any seemingly random point, and then be Hive food. If it is in his office then it probably is contained in some way that we can't see, or just a fake.

This is also another difference that kind of proves that instead of being a branch of the MCU timeline that split off in 2016 when the events of Captain America: Civil War went differently, it could just be a whole other universe in general like Earth-828 or Earth-10005. Some of the reasons for this include the presence of Norman Osborn, the events preceding that of Runaways going differently, and the events of Agents Of S.H.I.E.L.D. Season 3 going differently, because by this point in the 616/199999 timeline, the Monolith was detroyed, and before that it was in the possesion of S.H.I.E.L.D., so it is possible that this isn't a branch, but another universe.
Doesn't Norman Osborn know that the monolith is a safety hazard?
