Plagiarism detection is only needed because we are using completion/grading of work to determine whether students graduate, GPAs etc. The article is arguing that we shouldn't be so dependent on the "grade of homework" metric at all, so plagiarism should be less impactful and less incentivized.
I have seen students plagiarize co-op work term reports, which at the institution that I marked at are binary pass/fail with a near 100% pass rate (barring plagiarism). The assignment isn't long, is on a subject the students already know, and you can hand in some pretty terribly written garbage and still pass. But students still try to plagiarize on it - there's a subset of the population that wants the degree, but can't/won't put in the time to do the actual work.
