You're right, to a point. But many more employers will see one's degree, major, minor and GPA on one's resume than will look at a detailed course listing on one's transcript. A computer science or chemistry minor suggests a certain amount of coursework and skills in one line:
Education: Big State U, BS Physics (Computer Science Minor) GPA 3.9/4.0
Hiring managers see what's on the resume and may never look past the top few lines unless they are interesting. Most of the time, human resources personnel only bother with transcripts once a candidate is hired and only to verify essential information. Checking a transcript in detail related to coursework is rare. (It happens for some teaching jobs, but not usually for industry jobs.)
So sure, employers care more about what you can do. But they are sorting through a big stack of resumes to quickly narrow the field of candidates. What's at the top of your resume to make them take a longer, closer look at yours? Assume they're going to read the whole thing on the first pass? You lose.
