It's a terrible solution because it sets a price floor that makes it impossible for people to afford repairs. You need a $10 battery connector? 1% of 100k.

It's a vulnerable population who needs these parts. Probably lots of folks who can't work. Medicaid caps the amount of money you can have in an account at $8000 max. Pricing parts this way will push people into abject poverty out of desperation.

How about making parts for all medical devices something that must be covered by healthcare? Or, and this one is a crazy one, provide universal coverage so you can just get a new device at a reasonable price that's negotiated by the government?
