It's more fun, but your fun shouldn't come in the way of getting work done - or worse, getting in the way of others getting their work done.

I wouldn't say it's a matter of fun but often a matter of necessity in modern software development. Less experienced people can often have inflated egos and will refuse to listen to any advice from anyone else. Letting them fuck something up themselves (not too badly) after you've explained why it's a bad idea can be a hard but good lesson.
