In case you missed the full version, here's a bit of the problem.

The graded-card infatuation also is seen by many, this writer included, as a bad thing for the hobby. It has priced the collecting of sports cards out of reach for many. Complaints often are heard from collectors who send a mint card to a grader only to have it come back undergraded and not in the condition it was sent in.

Grading also differs among companies (a 10 from one company is an 8 from another) and, worst of all, there is the supply-vs.-demand curve that is now resulting in a lot of high-priced graded cards gathering dust in dealer display cases.

My main point being that grading and slabbing have only resulted in negative results for collectors and dealers, in the long run. If chippers can learn from observing other hobbies, we can see that we don't need slabbing and grading. A simple point.
