Why?
Because if you write down the Bayes' Rule calculation, that's not the ratio that appears in it.
"Typically" and "Generally" are doing all the beavy lifting there.
Nope. They both mean: for large n, for a fraction of sequences that tends to 1 as n -> infinity, that's what happens.

HTTTHHHTHTHTTHHTTHTHTTHTHHHTHHTTTHTH. Using Bayes' Rule, what are the odds I actually got that sequence, as opposed to randomly typing letters? (If you miss my point: You're misusing Bayes' Rule in this argument.)

If Alice cheats 100% of the time, your formula produces probabilities greater than 1 for any n less than infinity, which I'm reasonably certain doesn't happen.
Alice: "I just flipped a coin [large number] times. Here's the sequence I got:
(Alice presents her sequence.)
Bob: No, you didn't. The probability of having gotten that particular sequence is 1/2^[large number]. Which is basically impossible. I don't believe you.
Alice: But I had to get some sequence or other. You'd make the same claim regardless of what sequence I showed you.
Bob: True. But am I really supposed to believe you that a 1/2^[large number] event happened, just because you tell me it did, or because you showed me a video of it happening, or even if I watched it happen with my own eyes? My observations are always fallible, and if you make an event improbable enough, why shouldn't I be skeptical even if I think I observed it?
Alice: Someone usually wins the lottery. Should the person who finds out that their ticket had the winning numbers believe the opposite, because winning is so improbable?
Bob: What's the difference between finding out you've won the lottery and finding out that your neighbor is a 500 year old vampire, or that your house is haunted by real ghosts? All of these events are extremely improbable given what we know of the world.
Alice: There's improbable, and then there's impossible. 500 year old vampires and ghosts don't exist.
Bob: As far as you know. And I bet more people claim to have seen ghosts than have won more than 100 million dollars in the lottery.
Alice: I still think there's something wrong with your reasoning here.
