I agree. "Closure" is not the right word. Loving relationships should be not regarded as "closed", but as continuing beyond the grave. But for people grieving, making a loving gesture with the remains seems the right thing to do. The dead physical body is indeed dead, but it was the receptacle of a loving relationship and thus deserves the respect of a fit resting place.
For many people, putting a body or ashes in the loved one's favourite place is a good way of honouring loving memories.
