If we can't support this in Wayland we should hide the setting.
We should be able to implement this : https://wayland.freedesktop.org/libinput/doc/1.11.3/middle_button_emulation.html It should be possible to support. As a reference, https://phabricator.kde.org/D28296
This is not a Wayland bug. The same happens to me on the X11 session, but can be easily solved by clicking on another KCM and coming back. I've just tested with Wayland and the middle click emulation option was unavailable the first time I opened the KCM, but when I clicked somewhere else and back on Touchpad settings the setting showed up normally. I'm pretty sure it's just a bug with KCM, not Wayland specific.

Currently I can reproduce on X11, but I can't on Wayland. The bug occurs on X11 when I open Touchpad KCM directly via icon on desktop or via icon in 'Most used settings' section of 'Quick settings' page of System Settings. The bug disappears after switching to another KCM and switching back to Touchpad KCM, as mentioned in comment 7.

Created attachment 142991 [details] screenshot ops, as we can see in the screenshot attached to this comment, the bug on X11 affects right-click options (they are greyed out), not middle-click ones. I'm closing this bug. If anyone is able to reproduce the bug with middle-click options, feel free to reopen.
