I agree overall to the sort of gist of your post. Having said that, I still track down content scrapers (even though they've never outranked me) simply because it's my content and I'll protect myself from theft.
Regarding 1)a) though - I wouldn't agree with this. If you write great content and don't focus at all on backlink building, this is essentially what Google preach. (Granted, if you have great content you'll pick up natural links). However if someone scrapes your content then automatically gets tonnes of backlinks and possibly outranks you, it's not really your fault; it's the scrapers fault.
So yep, I'd agree overall; even though I disagree that Panda is a triviality and that being outranked by scrapers is a black-or-white issue.
