Meaning and form

What is the point of writing anything if it doesn't have meaning behind it?  In other words, what is the point of the narrative?  Does it cause the reader to feel any kind of connection or emotion?  

If someone writes with no kind of feeling, then the reader is going to be able to sense it, and will not be able to connect with the writing.  A reader wants to relate to what is in front of them, whether it's negative or positive.  If a person's writing is considered 'sloppy' and all over the place, the harder it will be for someone to enjoy it or feel anything towards it.  

Form is extremely important when writing.  If there is no trace of form or order, then the reader will just get bored and eventually stop reading.  What exactly is meant by form?  I feel as though form has to deal with the organization of main ideas and proper thoughts in order to carry out the significance of whatever the writer is trying to portray.  In John McPhee's "The Patch", his form is unique in the sense that he goes back and forth between writing about being in the hospital with his father, to memories of fishing in different places.  This is unique story telling, because it brings the reader to two different places all at once, while still feeling the significance of McPhee's father being in the hospital.  He correlates a hobby to the death of his father through memories and a rare sense of form.  Without these constant flashbacks, the story may be considered dull and ordinary.  Instead, McPhee causes the reader to feel a sentimental connection with him, that may not have occurred without the proper form.
