I don't like to be judgemental so I wouldn't say that everybody '
should' repair every punctured tube but couldn't you simply pass yours on to someone who is happy to? There are lots of us who would gladly spend a few minutes repairing perfectly usable tubes, saving money in the process, and reducing the amount of crap going to landfill every year.
PS If there happen to be any 'non-repairing' CycleChatters who come on my forum rides, feel free to offer me your dead tubes next time I see you! If they are easily repairable and similar to what I normally use then I'd take them off your hands.
