And thus, makes it harder to recognize where sentences end and begin. Whether you're talking about a character's name, or other noun. Punctuation is there to help break sentences down into recognizable patterns so one can read quickly and easily. Commas and periods help tell the reader to stop a moment. They let the reader know that these two words are not in association with each other. Just because you know how to read your sentence, doesn't mean that everyone else knows how to read your sentence.
When reading a sentence that has no markers or labels of pause, it's difficult to get the true meaning and feel of what's been written. I find myself re-reading a sentence three or four times because something didn't sound right while reading it. The reason I find, is because there should've been a pause between two words that I didn't read; and I didn't read the pause because there was no comma. So the lack of comma completely changed the sentence.
Same with capitalizations. Many nouns are used both as Names and Tiltes. If you compound them into the same format, then no one will be able to read the importance of The Hunt, or Mr. Hunter. To those who don't share your mind, capitalization is necessary for them to truly read what you're attempting to express.
It's more than just organization, and "it looks better." It shows that you want us to understand how you think, how your character relates, and how to feel about a certain phrase. Capitalization and punctuation allows us to see your characters and your world the way you do.
