I love how the closer we get to “the edge of the Reality”, the more it sounds like the ramblings of someone that got their hands on some of that GOOD stuff

You might want to read Dan Simmons' Ilium and if you can stomach some weird post-9/11 shit, Olympos. One of the overarching themes is what you describe... or similar.

> Some years ago I was playing with the idea that the Reality might invent new laws when people look for them, and doesn't bother with laws when no one observes them

There are several books from Greg Egan with this idea in mind: Permutation City and Distress. The latter one is exactly about this idea.
