Price? I have no idea what the markup on the touchbar is, but I'd guess it's at least in the $50 range, no?
When you're buying a $1650-4000 machine, $50-100 probably isn't gonna make potential buyers balk.
When you're buying a $99 keyboard, $150 is a fairly big difference. And honestly given the $99 price tag on Magic Keyboard, I'd guess Magic Keyboard + Touch bar would be like $199 at least. How many people do you think would buy it at that price tag? You also have to consider that Magic Keyboard currently works with windows, linux, etc, so the potential users are much wider than a Touch bar enabled keyboard, which would only work as intended with macs.
I assume it's some combination of price, performance, and battery life on the external keyboard.
You can use the Touch Bar on your iPad (using an app like Duet Display, or even with Sidecar if you have a modern MacBook). I find it to be useful in certain situations.
