Regarding her points:

  1.  No one has ever asked about my GPA.

If college is your terminal degree and you know you will never apply for a higher degree, that might make sense.

  2.  I didn't sleep.

One would hope that not getting straight A's wouldn't induce sleep, but instead would free up time to do more fun/cool/enlightening things. You'd still be sleep deprived.

  3.  I've forgotten 95% of it. 

Not sure that college is designed to impart information.

  4.  I didn't have time for people. 
  5.  Work experience is more valuable. 

These two seem reasonable.

Her point 2 claims she studied 100 hours a week to keep those grades, and averaged 3 to 5 hours of sleep a night. She probably hit diminishing returns well before the 100 hours, and would probably have benefited from doing other things and sleeping more. One or two nights without much sleep is OK, but doing that for an extended portion of time is unsustainable.
