You're moving the goalposts. There's tons we can do to improve US healthcare outcomes (we overspend compared to what we get [1]) by emulating what has succeeded in other countries. But that conversation and solution is different than "nobody has healthcare".

As to defense, I live here, as do the majority of the people I love and like. It's in my interest to have my country continue to exist as a sovereign nation with the ability to defend itself from foreign adversaries.
