I would say it's more like: "How can I do X?" "Here are some reasons you can't do Y."

The answers should have been "Here are some reasons doing X is hard, but here's an attempt at it anyway and also some more robust alternatives to doing X." That would have been an excellent answer. (If you go down far enough you do start to see things like this but they're hindered by people still responding that you can't do Y or downvoting because they don't understand what's happening.)
