It's kinda the classic, "I've always used XYZ responsibly and never had a problem. Doesn't everybody else do that?" People do this all the time with credit cards, alcohol, gambling, extreme sports, etc. You think that because you've always done it "the right/smart/responsible way" it must be equally as obvious to everyone.
