There is a subtle issue lurking behind. And that can be framed as a question: can one access things(say, numbers) that do not exist? If the answer is "Yes", then we don't need the Platonic world. Otherwise, we need to postulate the existence of numbers and sets in another world (Platonic world). You can also see people who are looking for Platonic love. In other words, it is an issue between access and existence. Does access need existence? For instance, when X says 'John is charismatic', is 'charisma' like 'neurosis'? Definitely not, and X sees John's charisma. And this charisma doesn't play the causal role.
