My simple answer is:
Using pointers you not able to copy the data.
Example:
You create a User struct and use it without point:
u := User{}
When you do this:
newUser := u you doing a copy
If the u was a pointer
newUser := &u you not doing a copy, all newUser data will be passed by
reference to u
I am not golang expert, but I think this is one possible answer.
Regards.
