For me, my drive for asking why was diminished by the sheer complexity and implications of some of the answers I was getting to the question. Like, imagine a giant fractal image. As a child, we examine that first level all over, and ask why this, why that, about that surface layer. Later, we zoom in with questions and contemplation far enough that the thing that looked small explodes into a whole new vista, a new layer, making the previous one obsolete.
Eventually, the existential "why" questions drive us to action, to death, to strange extremes. For me anyways. That's when I'm like 'Not yet.. I'm gonna find a secular hobby and just leave it alone."
I get what you mean though, about thinking that the questions are going to degrade the simulation experience.
