You are entirely missing the point. This only really exists when you are choosing unusual names.
Let's say I confide in my family and close friends that I am going to call my child 'Jeramiah McFridgeMagnet'. You might agree that this is a fairly uncommon name - it's not like calling your child 'James', 'Anna', or 'Simon'.
Three months later, one of my close friends now comes and tells me that they also have chosen to name their coming child 'Jeramiah McFridgeMagnet'.
Now, whether or not you believe the name is being 'stolen', the situation is still very strange. Why has the friend chosen to choose this name in particular? What sort of a signal are they attempting to send by choosing the precise name that I too chose? Why could they not come up with something else more original? Why would they undermine the originality of my choice? >

Honestly I’ve seen people getting upset on common names like “Lily” or “James”.
