I have two responses to the original post. The first is that much of what you said is true. Landscape photographers do tend to follow rules and look first for technical excellence.
My second response is, str8talk83: how arrogant. While it's true that little photography is deeply creative or new, it's also true that if the photographer likes it that's good enough. Or am I photographing to please your aesthetic? If it also happens that editors, judges or gallery visitors like the photos enough to buy them or award prizes, so what if the work looks like other's? At least it's accessible.
Creativity is wonderful. Engaging in it can be exhilarating. But it is not the only reason to photograph. Having your wife, or friend. or photo club buddy say, "oh that's nice," is good too. We are hardwired to seek approval. And I guarantee you that more people will comment positively on my landscapes than on my photos of discarded tires or my grainy black and white closeups of hands. Besides, sometimes it's nice to just shoot a technically good but "typical" photo.
So often when people put themselves as arbiters of taste or creativity the work they ooh and aah over becomes successively more and more ingrown, until only the in crowd can appreciate it. Calling the ordinary boring is so elitist.
I will refrain from sharing my squirrel photos, though they are cute. But here is a landscape that doesn't look like an Ansel Adams:
