It is indeed 'artificial' in the sense of being deliberate human functioning. But it is not necessarily 'artificial' in the derogatory sense of being false. The use of analytical thinking applied to the aspects is discussed in more detail elsewhere . However, I do find them extremely useful, and in particular the clear distinction of the aspects. In these days of the decline of rationalism and rise of interpretivism, I find Dooyeweerd's aspects a useful corrective to both.
Rationalism says there is only one aspect, and all others are merely emergent from it.
Dooyeweerd's aspects counter this. Interpretivism says that there are no aspects at all, and all is merely interpretation. So the world gets fragmented. Dooyeweerd's aspects counter this too. I find this useful in both information technology, to ensure that I do not ignore some important factor in a situation.
