You don't need a trained eye to see its beauty. Some manifestations of nature do demand more interaction and engagement with them in order to appreciate them better, such as the desert. Still, natural charm shouldn't go against your natural endowment for beauty. Natural landscapes have no fixed boundaries either.
Human invented art or art form long time ago, which had no fixed boundaries either. Later, people conceptualized them and pretended that art forms are preexisting objects. But in reality, there was no 書法, people invented it. It came into existence because it once looked good. If someday it doesn't look good, then it isn't shu fa.
I think 姚順 shu fa is OK. 立 shu fa is sometimes OK, more often terrible. Li contradicts himself by trying to take advantage of shu fa's preexisting status while denying the qualities that established its preexisting status.
