I agree, but with the caveat, "provided you don't bang up the rotors."
The operating principle requires that the rotors flex. Thus, they are not stiff enough to resist bending when struck from the side. When this happens, they'll need straightening.
Other than that, I go thousands of miles on my disc-brake equipped road bike with hardly a thought about them.
I don't know a thing about mountain bikes, but yours sure looks nice. I hope you enjoy it.
