punch drunk, scammers don't have a moral compass.

Are you worried I've let out some kind of state secret and now all the sellers will start sending empty boxes to their buyers to scam them out of a few dollars?

Its not a good idea to let the wrong information stay on the boards without being addressed. You DO only need proof of postage (as outlined in the policies) for seller protection, if you are not happy with that then perhaps you could take it up with someone who has the power to change the laws.
