I don't know why your repeat the same mistake with 10k, "typical" doesn't mean you ignore the atypical, that's still a net benefit.
Your last point is also misleading - no, you don't require the equivalent to master password, and yes, it still makes sense in that case. "Shorter/easier" can still mean enough entropy for the smaller threat model of local compromise (with even more entropy required in the master password for the bigger threat of cloud compromise). It's when it drops down to the level of literal 4-number PIN, then it becomes useless against this threat and only useful for an even smaller threat
