OOP makes use of access modifiers to control the accessibility of methods and properties. This is what allows you to use the concept of encapsulation, so that you have a public interface that consumers of your code can develop against, as well as a private implementation that needs to be treated as a black box from the outside.

Having all of your methods and properties be public generally defeats the purpose of using OOP in the first place, as most of the benefits depend on the concept of encapsulation in some form or other.
