I have seen that same argument that things don't have to be designed for the worst case scenario on our robot. Why do the construction properly the first time when you can just fix it in competition. Why over design something the first time when you can just make it work temporarily. It's things like that that make a huge difference.
Especially in elims, when that part that wasn't designed/built right fails suddenly because it took a load that it couldn't take.

Do it right the first time, and it'll keep going. Right, Mr. Lavery?

As for "How could a T-shirt jam?", most launched T-shirts are wrapped somehow for distance reasons. Usually, it's a rubber band or three. Guess what? Said rubber band or other wrapping has a much higher coefficient of friction than a T-shirt, and may stick in the barrel. The T-shirt then sticks too, and you suddenly have a jam. Now you have pressure that can't get the shirt out and can't go elsewhere. Your best bet in this case is to drain pressure immediately and use a stick to remove the shirt, but sometimes, it takes care of that for you, in spectacular fashion.
