The brick walls are there for a reason.

Ah, I'd forgotten that part. And now that you remind me of it, I remember that I intentionally started the quote after that line because I didn't like it, for reasons similar to the ones you brought up. I now concede that he did seem to imply that keeping unmotivated people away from what they want is desirable (although I expect he would object if someone put it that way explicitly). He still mostly focused on getting around brick walls rather than leaving brick walls up, though.
