The company is a distinct entity. It's capital and assets are held apart from the investors for the traditional reasons. Are share buybacks always in the best interest of the company? I'd argue that they're nearly always in the best interest of investors only, especially when accomplished via selling assets, selling assets and then leasing them back, or just straight out taking on debt, that they harm the company, and accordingly, the employees of the company.
