The medical system is stacked against people with executive dysfunction. If you can't make timely appointments and argue with insurance you'll actively deteriorate. Not even counting things like remembering your meds.
I've often heard of elderly people who've got so many prescribed drugs that they begin doing really badly, and some whiz physician intervenes, sweeps away all their prescriptions at once, and suddenly the patient is doing far, far better. I've also seen friends of my parents who were so utterly bogged down by all the requirements, and my Dad valiantly authored spreadsheets and managed the regular refills and all that stuff for them. And my Dad is not an HCP by any means.
It is obvious that clinics and prescribers can effectively put a "leash" on their patients by tying them to at least one specific medication that keeps them coming back for more, on a regular basis. If you cannot live without your prescription, then you will learn to be loyal and compliant with your prescriber and your pharmacy.
The taking of medications is analogous to the sacraments of the Catholic Church. There are specific rituals to be followed for each. There are specific substances to be taken. We don't really know what these substances are (the Hebrew word "manna" actually means "what is it?") But the priestly class decrees how they are to be administered and taken. And obviously, we cannot have life within us if we do not partake in the correct sacraments.
And that is why I strictly limit the amount of medications that I take, because it is a slippery slope to being bogged down in intricate daily rituals, fasting, abstinence, and appointments to go get more.
