hahah was just gonna write about this, but you beat me to it.

Either way, the point is, there's a trade off. Kinda like the 80-20 rule. It obviously taken 20% effort to protect against 80% attacks (the casual opportunistic attacks. like preventing sql injections, or locking your front door) and it takes 80% effort to prevent those last 20% attacks (actual Pros). SO "you might as well not have bothered" is somewhat naive in my opinion
