Well to an extent the more refined or specialized something is, the more this takes care of itself.
For example with a physics conference, you probably won't have to bother excluding people. Relevant people will know how to get there, or will be invited, and most others will probably not want to be there anyway.
Considering that, if a disruptive person does get in, then it's just bad luck.
That attitude used to be largely an American (U.S.) attitude, which I think has a basis in the notion of rights which is so central to that society. Most Commonwealth countries mainly focused on responsibilities. However, IMHO the American focus on personal rights (even in the most mundane, relatively insignificant aspects of life) has spread increasingly into other English speaking countries in about the last 15 years.
Here in Australia, you would never get children acting badly in public places, without the parents basically going to whatever lengths necessary to restore reasonable order. I think people had a very strong sense that it was their responsibility to ensure their children didn't disrupt other people's affairs. However, in the last few years it seems to me that people are more focused on their right to be in a particular place, irrespective of how it might impact on others.
Perhaps the focus on one's rights doesn't make for people making good neighbours. This meshes with my experience of Americans being the most individualistic English speaking people.
