I agree with everything you said, except, I do see good reasons for Church or gathering together regularly for silent contemplation and community.
Especially, because many churches tend to open their doors and socialize with people who may not fit, socially, anywhere else.

The Unitarian Universalists are a nice example. And they have a great sense of responsibility to community service and collecting money to put towards great causes. They tend to quote great literary works or spoken words of great minds in their sermons, extrapolating the wisdom of man in order to emphasis their message for the week.
