But why? What's the point of all those hoops, other than to discourage new users?
Well if the question is a legitimate duplicate then it is clearly a win for everyone, not least the one asking the question, since now you have a link to answers to your problem which have already been written. Which means now your problem is solved.
The asker can edit the question to provide more information and the question can be nominated for reopening. It only requires 5 votes to reopen, IIRC.
