It's a complicated issue however there is a difference: film stars make money from being famous. The more well known they are, the more money they get for an appearance in a film. Being famous is just as much their job as acting.
I'm not saying that they therefore have no right to privacy - I'm not even sure exactly what my views are on the issue - but there is definitely a difference.

This seems like sloppy thinking to me. Becoming famous is a potential side-effect of their acting job. With fame comes other opportunities, but that doesn't make being famous a job. Who is the employer?
Likewise, getting a good night's sleep brings opportunities to excel that might not otherwise be available. It doesn't make it my job.
