I'm not sure where you are going with this thread. Per number two my opinion doesn't matter. Keeping that in mind I'll try to be brief. 
There are both good and bad points here, but I would re-arrange the lists. I agree with maybe 20% of what you have here.
"Price stupidly low" is not something I recommend. Nor is avoiding permafree. My best series has a permafree funnel and the rest of the series is priced at $4.99. It makes me five figures a month with a 20% sell-through. I have not advertised since December.
KU is for shorts, new books, or people who need exposure. Its a tool as well as an alternative marketplace, not an end-all-be-all, unless your books fit the model.
Your protagonist needs both faults and things they excel at to be memorable and to keep the reader interested in what happens to them. People don't read the story to get to the end, they read it to find out what happens to the characters. If that character is "the most normal and good person you can find" it will be hard to make them interesting enough for the reader to care about.
You can and should sell at stores outside Amazon. Unless your book fits the KU mold I mentioned above you are simply giving up on millions of potential readers and affiliate money. Amazon accounts for maybe 50% of my sales, the rest are across the other platforms and growing every month.
All books are different. Getting people interested in them can follow many paths. I don't think there are many absolutes in this game, but there are many that come close. Most fall into the common sense category. Editing, coverart, research, formatting. These are all important, but without a good story it all amounts to a well dressed-pig.
That said; Will my way work for you? Maybe, maybe not. But its working for me very well. Find what works for you and discard the rest, keeping in mind there are no absolutes. What works today way not work six months from now.
You asked for a tip. Here's mine: "When at the gym, never take advice from the guy who is in worse shape than you."
My 2 cents. Free and worth every penny.
