I'm afraid it doesn't. To the contrary, treating effective security in terms of how it influences the attacker's cost-benefit tradeoffs, and evaluating proposed measures on whether the effort threshold they create is enough, is quite literally the opposite of black-and-white thinking.

And in this case we can clearly see that a solution that (a) does not substantially increase their costs -- and in fact, as I've pointed out above, only really filters by motivation, not by time, money or effort, and (b) doesn't target their potential benefits at all, is one that isn't likely to be effective.
