> Imagine if your job was booking plane tickets all day. United could provide you an API key to do so via an API, but in practice they won't, only some enterprisey travel software company can get that kind of access, for a steep fee.

Even your example sounds sketchy though. If you're not legitimate enough to use the enterprise software, why are purchasing tickets all day? And why do you need to proxy your bandwidth instead of just accessing the site directly. And why aren't you concerned about the fact that it's a crime to bypass the approved channels by hiding behind the proxy to do this?
