It's akin to buzzing the tower in Top Gun. It's showing off that you're a hotshot - part of the psyche that makes for a good officer in the first place.
I'm really rather surprised that so many (young?) viewers don't get that.
I understand wanting to do something daring and that's why I suggested that the Starburst should not have been written where it resulted in an expulsion and shame if you attempt it. It should have just been a really hard, really dangerous trick that nobody had ever done successfully. That would make sense for young people to risk their lives for the glory of succeeding. If you succeed at it, you would be a total hero. That would make sense that the 'jocks' as someone called them, would try something like that.
The way the Starburst was written in the actual show was that it was totally against the rules and punishable by expulsion. Starfleet would not turn a blind eye even if you did it successfully because that would set a very bad precedent (i.e. why make it against the rules if doing it is okay?). I likened it to Drinking and Driving in my early posts where it's wrong and against the law. Just because you drove home pretty well won't make the cops look the other way. So, the issue isn't about young kids wanting to do something dangerous, it's why they thought everyone would be cool with it if they did it successfully.
