I don't have a particularly strong opinion on that one way or the other. The one I had worked fine for two years, then it broke. So I wouldn't buy another one (of that particular model) because I had a bad experience with it.
Happy to take this opportunity to spell it out for you, though.
No, it wasn't a stupid question. It was a brilliant question. You insist on oversimplifying it to fit the answer you want to give. Of course you will replace the crank. That is so obvious it can't be what was asked. The point is what do you do if you believe aluminum is safer than carbon and that breaks too. The question is about how do you cope with an imperfect world in which nothing is absolutely safe. Pretending that you can depend on aluminum may be satisfying but it is not effective.
