My point was that it happens that right now the US government spends a per capita amount on healthcare (for Medicare, Medicaid, VA, Military etc) that does not provide universal coverage but would be sufficient to provide universal coverage at the per capita cost of it in other western countries. It's an artefact of the substantially higher healthcare costs in the US.
Govt cost per capita for medicare is a measure of its efficiency, but not that its already funded for everyone.
