I hadn't seen this article. Pharmacists have been pushing this since I was in school sooooo long ago! The theory is that mass marketers couldn't offer these specific, highly misused or abused medications. Honestly, any pharmacist who is allowed to escape the filling counter to help a patient in the proper OTC product selection probably doesn't need the BTC to protect his business.
An example is pseudoephedrine. Currently, you must sign a log to purchase it at the pharmacists counter. How many times has the pharmacist asked you about high blood pressure, diabetes, or thyroid conditions before he sold it to you? Just because we have the exclusive rights to sell it doesn't mean we actually do anything to earn the right.
