I get what you're saying, and you're right, but trying pointless things that obviously won't work isn't going to help. Thinking of better, innovative ideas will. I wish I had one to give, but obviously none of us do or this problem would already be a thing of the past. More possibilities will arise as technology progresses too. I don't think that not pursuing that particular course of action is "letting the world burn," and in the meantime, even if we do pursue it and watch it fail and burn, people still need to learn to deal with this sort of thing until something does work. Its not a fun part of life, but it is part of it.
How do we know something is pointless unless it's been done?
