This is such an elitist take of the situation. One person may not be gullible enough to unintentionally run a malicious application, but once you extend it to a group of people, the claim will likely no longer be true. What if your coworker(s) accidentally ran a rogue X11 application, their passwords got keylogged, and now your company systems are compromised? And the above paragraph only operates under the assumption that you, the one person, is perfect, who never makes mistakes, never runs malicious applications, and runs on a distro that is never compromised, providing programs developed by people who are security-minded. You might have been compromised never knowing it. On the other hand, the other day when I shared my screen on Firefox, my Wayland compositor (indirectly through xdg-desktop-portal) asked me to confirm that it was my intention to let the browser see my desktop. I felt that was pretty nifty.
