You don’t have to write your name on your property to know it’s yours. You don’t need a (c) symbol and your name to be able to lay claim to ownership.
But if someone takes your property it’s helpful in getting it back if the thing they claim to be theirs has your name on it.
With copyable property, especially where copying might reasonably be expected such as with source code or content on a website, it’s helpful for other parties to know who they should ask if they want to take a copy. (The license may also require that the original owners name be included on copies.)
You can also put the license right there too. Especially if the license is “no license” aka All Rights Reserved.
