Here's how your story "reads" to me. You wanted to comment. You couldn't. You experienced frustration. You might have even believed you were in a Catch-22 -- that your lack of rep was keeping you from doing the only possible thing that would gain you rep, commenting in order to gain the clarifications you needed to answer a question. (Error 1.)
Then you said to yourself "I bet NOBODY at Stack Overflow ever considered that before! If they knew about this, I bet they would change the rules!" (Error 2.) You went straight to your keyboard to ask the question, phrased in an inflammatory way that demonstrates you believe the issue is nobody thought of this before, on the wrong web site. (Error 3.) Why not, right? You want to tell people how something should be run, the last thing you want to do is invest 10 seconds in seeing how it's run right now, eh? You used terminology (article, thread) that does not apply to SO and SE, and often upsets the SO-is-not-a-forum crowd. (Error 4.)
You didn't do any looking on either meta (the per-site meta.so or this sitewide meta.se) into this issue. (Error 5.) I know that because it's raised CONSTANTLY so you would have known that people are aware that not being able to comment does frustrate and slow some people, but have decided the benefits of restricting comments outweigh that cost. You would also have learned a number of ways you can earn 50 rep without ever commenting. Simple logic tells you that the millions of current users with 50 rep all got there without commenting. You would have learned all of these errors before you ever committed them.
But you didn't. Instead you were rude, pushy, and hasty. On any site that is likely to get a question downvoted for being of poor quality - "not useful". On Meta, where downvotes can also indicate disagreement, it will happen even more so. And yes, downvotes sting. They are supposed to. You could now stop trying to suggest improvements to the site and network, or you could take a moment and learn what has already been done, how it works, how changes happen, why certain rules are the way they are, and how rules change. Hint: not by being rude. Ever.
Welcome to Meta. It's different here, but you'll like it once you get used to it.
