Nothing wrong with what your are doing if it works for you, but I wouldn't describe your workflow as trivial, and I wouldn't call using Password complicated. The value to me of 1Password is: Go to Website, Right click 1Password, enter password, logged in. No copy paste, no switching windows, no launching emacs, no searching through a list. Even the added friction of 1Password took a few starts and stops to get through. For people like me, your solution would quickly devolve into reusing a common password.

The 1Password workflow on iOS is more similar to what you describe because there is no browser integration, and I strongly dislike the experience. I often will abort doing things on mobile so I don't have to bother app switching and copy pasting.
