As others have said, your #3 point is controversial, but potentially not as bad as they seem. This really depends on what resort/part of the world you are. My home mountain in Oregon is about 65% black diamond, and there's only one green circle run. The first blue square you can use is actually very steep and quite dangerous for beginners. At the same time, I was living in the Midwest a few years, and the only black diamond I found honestly wasn't even as steep or interesting as the intro blue square I mentioned before. So, your advice might be accurate in context of a beginner mountain, but at many resorts blue diamonds are best left to intermediates only.
