The Sudbury Hill stations are certainly very close.

The philosophy of "we don't need to stop the Chilterns there because the
tubes stop there" is certainly very strange

It might be because there isn't demand. How heavily used are the trains
that do stop there?

Of course, this is probably one of those cases where ridership is low
because the service is so poor. If they had quick trains to Marylebone
every 15 minutes, they might see a lot more use.

Passengers use the Piccadilly line because there's a train every few
minutes. AFAIK Sudbury Hill NR has never had a frequent service, and there;s
no way that even a 15 minute service could be provided without significant
disbenefit to passengers from much busier stations further out. AIUI the
only times Sudbury Hill NR becomes popular is if there is a tube strike.
Passengers sometimes find the quick journey into Marylebone a pleasant
surprise, and carry on using that route for a while after normal service is
resumed on the Piccadilly, but soon drift back, perhaps after they've been
delayed and miss their train.
