I assume you write fairly "static" software that knows its job pretty well in advance. Ada programs tend to use a similar allocation strategy.
A lot of programs written in C and C++ are very dynamic, and may need to massively increase or decrease the number of objects they use while running. For example, consider an audio workstation: when you first start it, it has very little to do, but the user can add literally hundreds or thousands of tracks, each with dozens of effects and modifications.
Each of these features is composed of many objects. Ownership comes in when these objects have complex relationships, where one object may need to be referenced by many others. When it is time to clean up some of these objects — for example, when a user deletes a track in the audio workstation — you have to know which of these shared objects to delete. Ownership is one way of modelling that problem.
Languages that talk about ownership try to optimize the "best case" where an object has exactly one owner, because then it's very simple for the compiler to free that object. The trick is that you have to prove that no one else is using it, or else you have memory errors.
