    ...that the universe must be as it is, because, if it were otherwise, we might not be here to observe it.

Perhaps the grandest tautology ever spoken!

Also, I don't understand this line from the essay:

    According to the it from bit, we create not only truth, but even reality itself--the "it"--with the questions we ask. Wheeler's view comes dangerously close to relativism, or worse.

Relativism, at least maybe a muted form of it, must be part of our understanding of the world. There may be an absolute truth, but I guarantee we'll never discover it with our senses. There is likely a mathematical truth, but physical? experiential? historical? Hardly.
