You don't have to instantly resort to faith every time you hit a stumbling
point. You pause. You wait. You ask yourself whether there's a way around
the stumbling point. The instantaneous resort to faith is not act of a
rational mind, it's the act of a mind that was looking for an excuse to
resort to faith. Rationality is not so easily balked.
And with that said... why would rationality have any trouble dealing with
the possibility that our universe is a computer simulation? How does the
proposed objective fact that our universe is a computer simulation in any
way obviate the notion of objective reality?
And how does faith help in the slightest?
