Ya, upgrading your profile here to premium allows you to post all that. 

I am working right now and overlooked the part regarding the profile privacy setting.... I don't have an answer as to why it's that way, but I can tell you how I am setup that works for me:

Limit visibility of profiles, and all links to 'persons' within Navigation so Unauthenticated etc users cannot see, only standard + users. Then a members profile can be set to 'public' but still only be visible to site members.
