Whenever I read comments like this, I know that it is someone that has switched from another OS. macOS is neither Windows, KDE or Gnome. An awful lot of the functionality that you deem 'nonsense' comes from the days of classic Macintosh and even from NeXTSTEP.
In fact, nearly all the complaints I see in this and similar threads come down to people expecting macOS to behave like their previous OS did, and being surprised that it doesn't.
Nonsense default behavior, slow as heck, search barely works, keybindings are totally illogical.
It's totally unacceptable.
