Applied religion?

I wonder if there is any relation between, say, the desire of many to admire objects, or have idols, with the need of many to have a faith, a religion. I am, in this particular case, talking about the following piece of news:

My reaction is: Who cares? But, apparently, many do. Why? What is the need that drives them to do so? Could it be related to the (their) need for faith?
