Hi John,
the main reason is for the search function: when a user perform a search within a website the search functionality looks in the post_title and post_content.
I don’t know if is there a way to search also within a flexible content fields.
Another reason could be the export functionality. This way you can export all posts for using it in another website that has not ACF plugin installed.
Maybe another reason could be the REST API functionality, but currently I’m not sure about this.
Let’s say that, in specific cases could be useful having a method for merging and putting flexible content fields in the post content.
In my case the flexible content is used as page builder and replace completly the post content editor.
Anyway, actually I don’t need to display this content.
