The issue with this perspective is that corporations generally are not chartered such that they provide their employees with a voice in its executive actions. There’s also a level of (soft) coercion in that employees’ jobs are on the line. As a result, granting a corporation blanket rights (eg to donate money) is not implicitly granting those rights to the group, it is granting them only to a small number of individuals within that group. You say “individuals can exercise their rights through a group”. Most individuals are in fact prohibited from exercising their rights during working hours beyond what is of interest to the corporation, and do not have a direct voice in what the corporation’s goals are. Thus mediating privileges of a 10,000-person organization as if it speaks with the voice of 10,000 people is effectively reassigning the voice of a large chunk of people to a much smaller chunk of people. If the group only has the legal rights collectively as the sum of its individuals, it is creating an inherently non-democratic power block within a democratic society.
