Agreed, but I'm also not sure that socially anxious people are denied opportunities to observe social behaviour. I think it's more that when you are socially anxious, you don't feel entitled to participate in social behaviour and/or you believe that social behaviour is somehow wrong. Socially confident people can make the most out of a trip to the supermarket. Socially anxious people could be at the hottest party in town and convince themselves that they must stare at a wall at the back until they are allowed to go home.
