All this to say "yeah murder more people its good because I can't tell what is good or bad", an absolutely crazy take.
It's the exact same thing as "defund the police" except applied to the entire government. If policing is net negative, reducing it will save lives. If this government program is inefficient / worthless / net negative, cutting it or disrupting it will save lives.
If nothing else, the opportunity cost of a few hundred billion saved eventually, even if it's just a small fraction of US total government spending, can be used to save or improve many many many lives.
Hyperbole like "yeah murder more people its good because I can't tell what is good or bad" doesn't help.
