nobody calls touch controllers just 'controllers'.
and right off the bat i contest that touch, or even game controllers, are more 'intuitive' than a mouse or a keyboard. how can you possibly say a keyboard is not intuitive? it's a plank full of buttons with labels! it doesn't get more intuitive than that. they're just shouting at you to press them!
what you can do with them is another matter, and that's completely subjective, it depends on cultural factors, on each specific application and on how the particular interface is implemented.
as en exercise: fire up ed in vr, use your touch controllers, see how far you get. yeah, i guess you could use them as a generic 'game controller' split in half, i don't even know.
i've used game controllers quite a bit, have a few of them lying around, still use them occasionally when at friends', and still don't like them. i also use touch and like them a lot (if the app is properly implemented, not always the case), i see a lot of potential in them ... but i just much prefer my keyboard and mouse for most things. for a flight/space sim, nothing beats a joystick/hotas.
you are quick to call others stupid (luddites?) but seem very keen of considering any new thing better and obsoleting anything prior just because it's newer or it's the current fashion. not everyone dives directly into every new fancy just for the sake of it, and just uses what best suits each job and his own preferences.
