You don't want your story edited.
Editing is a good thing. A good editor can add consistency, catch grammar mistakes and typos, and give you a perspective you haven't thought about. If you want to self publish just because you think an editor will slash your story to bits, think again. An editor is not against you, they are working to help you and if you can't handle seeing your mistakes in red (or think you can't make mistakes) then you need more learning time before trying to self publish.
You will be a successful author without a major publishing house, thank you very much.
The self publishing world is just as harsh (sometime harsher) than traditionally published venues. You don't have the added cushion of a publishing house and you have only yourself to rely on for networking and sales. If you think self publishing will be the easy way to ride around rejection, you have another thing coming! There is also rejection in self publishing that comes from readers.
Perhaps this is related to the above point, maybe not. In either case, if you think it will be as simple as putting your work out there and making tons of moo-lah, you're in for a surprise. It doesn't work that way. In much the same way that content writing works, so does self publishing; the more you write, the more you make and it may take a long time for you to make enough to smile at.
The point is, if you self publish for the wrong reasons, you'll find yourself quickly frustrated with it and wanting to give up. First and foremost, if you're going to self publish, you should do it for the passion of the art of writing itself.
