But I don't think "fake human-readable" URLs break the analogy with physical addresses. There are many different ways of writing the same address:
987 Some Avenue West, Unit 123, Brooklyn, New York, NY 12345-6789
Unit 123, 987 W. Some Ave., New York 12345
123-987 Some Av W, NYC, NY
And the numbers aren't just opaque identifiers (except for the zip), at least if you're walking down the street: you know that 28 is next to 26, opposite-ish 27, and halfway to 56. There's nothing that corresponds to walking along the street on a website.
