I know commercial real estate contacts are more complicated than just a lease. Plus companies lose tax incentives from local governments that outweigh any any power and building staff costs. The problem is its not the lease that’s required to get those incentives. It’s butts in seats and with commercial real estate contacts they may have to pay a penalty if people are nit using the building because the building owner may have contracts with city to make sure that buildings traffic is supporting other businesses around the office building that may be owned by the same people. Note I think the whole system is stupid but it’s more complicated than just sunk cost.
