Hhmmm your contention is that insurance companies deny care. Does that mean that Medicaid and Medicare will pay for whatever care you want? No limits?
Private rooms? Specialists? Brand name drugs?
It means it would not be a for profit endeavor, meaning increased profit margin growth to infinity would not be the primary goal of the administration of healthcare, and coverage would be, wait for it, universal. All the advanced post-industrial nations have figured this out, we're not "exceptional" enough to. And yeah, for profit care gets rationed.
