Your linked to article does not demonstrate what you claim it does. Your reasoning is wrong.
Medicaid expansion was a big part of the ACA.
> "Findings suggest Medicaid expansion under the Affordable Care Act saved about 27,400 lives between 2010-22, including among younger adults."
> "Their findings show that Medicaid expansions led to a 12% increase in enrollment and significantly reduced mortality—not just among older adults, but also younger ones, who accounted for nearly half of the life-years saved."
Huh? Did you read it? My point was that we could have just expanded Medicaid to achieve this.

Well see, first you narrowly define the ACA to be "everything that didn't help"...
