This is not an opinion site: it's very unlikely that there will be 102 votes for and 101 votes against. That happens in political discourcediscourse nowadays, but it should not happen on a site like Emacs SE: either the question makes sense, follows the rules, has not been asked before - OR not. That's not a matter of opinion. Either the answer correctly answers the question and/or is useful - OR not. Again, not a matter of opinion.
The 1000 point rule is to prevent people who have no stake in the site from doing damage (either accidental or malicious). It's always possible for somebody to stick around, get 1000 points and then do damage, but the vast majority of people are here for the help, not for doing malicious things (and any exceptions can then be handled individually: users can be banned by moderators).
Think of it as "getting your driver's license": you need to show that you are responsible enough to "drive" around Emacs SE.
