Why do I need OAuth for using Public Streaming API?

Please help me understand the following:

If I tend to use public streaming API which should show me the flood of all tweets (regardless of the user) why do I need OAuth?
And who is going to be the user granting OAuth permissions in this case? will it be the application user id itself?

Our Streaming API system is user-centric and role-based. Historically, the account connecting represents the application – they are one and the same. For the purposes of connecting, the user token that you use should be the owner of the application.
