Why are there statues of her?
Are there statues of just her? No. Are there statues of Christ and other saints? Yes.
The statues are there for the same reason why any statue is built, to honour and commemorate her.
Now, again, do you believe it is right and proper to have statues of Christ?
There is a difference between having a statue as a decorative piece of a place of worship and a statue that is often the focus of rituals. IE the crowning of Mary.

Sorry; that’s a no-no.
