Welcome to the forum!
No worries about thinking you're talking down, you have your views and you're free to express them
With that said, the act of registering with search engines is useless in my opinion - in the sense that it's redundant work.
Your time is much better put to use in obtaining backlinks to your site, not registering your site with search engines.
With obtaining backlinks search engines will find your site nevertheless, so why even put your time in something that is bound to happen?
