Darksoul: in table tennis (which I play), it is not you against the ball, it is you against the other player. You play ping-pong for your enjoyment, and others do as well, if you cheated, then that would take the enjoyment out of it bacause you could win easily.
With folding, you are not competing against anything persay. you can say you are competing against your own skill......ummm.. either way, no matter what you do, there will always be a model more advanced than your skill level, no matter what you do. In most cases, glue is used to make the model look better, fine, do what you want. Glue is not going to help you fold the model (in most cases, not always). Tools just help you a little bit. kind of like using flippers while scuba diving, it helps you along.
By the way, I do not use glues (except for one very unstable moduler), I don't use cutting, and I use the occasional little piece of something to help in those tight spots (you know, like when fold the Ancient Dragon out of 2 CM paper

) lol. If I am attempting a personal record, I don't use any tools, for instance, folding little cranes, I don't use any tools, just me and my fingers (I don't have long finger nails either).
But whatever, do what you want, origami is not a competitive sport, it is an art.
