Let me go even further. Why not get a 30% cut of every single credit card operation validated through that bank's iOS app? Why not get a 30% cut of every wire transfer done through that bank's iOS app? Why not get a 30% cut of every national tax declaration submitted through an iOS app? Neither of these is physical.

I actually wish they would do this. It just would go to show the power we are bestowing on these "gatekeepers" while governments keep pushing more and more vital services as "apps".
