<p>It's a feature, present throughout SE, to defend against the hordes of off-topic misguided comments that would appear without such a restriction.  (The community closes tens of answers-cum-comments each day as it is.)  As a moderator I would just love to be able to grant people like you higher privileges instantly, on the evidence of goodwill and intelligence you have already provided, but I have no such power.  About all I can do is cheer you on and encourage you to ask good questions and provide good answers in oder to attain the needed 50 points.  It only takes one average answer, actually: five upvotes will do it.  (I have been able to use my voting privileges, as a community member, to grant you five of those points. :-)</p>
