He ask about my mother , I told him my mother was good at home He ask me my location and I told him I was at work. He then told me what is happening.

So the bolded helped stop the scam you said happened. It's actually an important feature of the fiat world but implemented wrongly. Such scams would probably have scaled through on Cryptocurrency due to anonymity feature. But the feature is very useful when dealing with strangers or when operating in public/trustless environments. Nothing stops a cryptocurrency from safely verifying and linking the identities of its users(who need to) to their crypto "accounts", so that they can always share the identities with families, relatives, friends etc, when necessary.
