You're absolutely, completely, 100% correct that the nature of good institutions is to make the virtuous path the easy one, and also that medical norms and practices do a (generally) good job achieving this.

You're also missing your interlocutor's point.

> Why would I want to make it difficult or put impediments in the way of my doctors doing their job well?

Doctors very often don't do a good job with complex cases - like rare conditions, complicated histories, or multiple interacting factors - and some will treat the patient as "difficult" or "an impediment" when they (the doctor) haven't grokked the situation. Very few patients are trying to be an impediment - 99% are trying to help achieve a good outcome, though sometimes their definition of that is misguided or impossible - but it is frustrating to be treated that way by someone who genuinely knows less about your situation than you do. ("Doc, I've taken that test before, and I've tried that medication before - I know it's not in your EMR, but here is a printout - what are you looking for this time that you expect to be different than before?" That conversation doesn't always go well - and even when it does, you're likely to be told "I can't [read: hospital / insurance policy won't permit] try something else until we've done those again" - so you'll end up going back to step A with each new provider.)

In fairness to doctors, many of them work within horrible constraints: it's impossible to get a handle on a complex situation in one twenty minute appointment every six months, and there's little point trying when it's likely the patient will be reassigned to a new provider by next year, anyway. The tension between medical ethics and practice and hospital (let alone, in the US, insurance) ethics and practice is enormous, and (for the individual doctors and patients caught up in it) intractable.
