Your post wasn't really egocentric so much as--and I don't mean this as an insult--ignorant.  And by that I mean that your suggestions were made without knowing that many of them have been made and rejected previously, and from what you wrote it's obvious you don't understand what the moderators here do and don't do (and will never do). 

When you register on a forum and start making recommendations without having all of the facts, it does come off as being a bit egotistical and presumptuous, but I don't fault you for seeing where some of the problems on the forum are and your willingness to speak up in order to fix them.  The problem is that the community doesn't have much of a say in how the forum is run.  It's pretty much all up to Theymos, and he's decided not to bring back the newbie jail and not to restrict them any more than the merit system currently does. 

In other words, the merit system was Theymos's solution to the plague of newbie BS that was at its peak in December 2017.  I think things have improved significantly since then--you weren't here in 2017, so you don't really have a sense of how bad things had gotten and how much the merit system cleaned up the forum.  Things certainly aren't perfect now, but it's better than it used to be.
