You absolutely can exit Emacs by clicking a button! Even when it is running in terminal. You just need menu-bar-mode (which is enabled by default) and enabling xterm-mouse-mode (which also should be enabled by default) - https://asciinema.org/a/rprH0gLSkrUz2cqr

You can: emacs has a menu bar and you can quit emacs that way. If you write code in your .emacs.d to turn off the menu bar, then I think you can be trusted to use the keyboard to quit emacs.

I think you're learning that Toast exists due to "skill issues."

You can exit Emacs by clicking a button, by making a mouse gesture, by telling it via voice command, by key-press, by modal key-chord sequence, by writing into a file, by selecting a menu item, by directly evaling (kill-emacs) command, by cookie in a file you merely visit, by a keyboard macro replayed from a register, by an abbrev whose expansion hook quits, by evaling an Org-mode source block, via a timer, via built-in solar and lunar calendars, by a shell command run inside Emacs that kills its own parent, by SIGTERM or SIGHUP from outside, by closing the last frame under the WM, by an LLM agent with an eval tool, and by pulling the power cord.

"I don't think" is never a good argument for making wide claims about anything.

Vim has full mouse support. Not only can you exit, but you can even save using just the mouse.
