There's literally thousands of items in game that ask the confirmation to toss them. Perfect example is dynamis where you could be tossing 50+ items in a single run. Whether you like it or not, accidents happen. I feel like some one shouldn't be penalized for a 2 second mistake on something that can take 100+ hours to obtain, when fixing it would really take minimal effort. And no, not everything should have this option, but the big things like R/E/M and ebisu's should.
