why not?
I don't like certain things the army does. why are aren't they self-sufficient?
or the parliament?
or education?

you're just picking on something you don't like or don't see the inherent value in.
not everything can be valued by the dollar amount.

self-sufficiency is just a myth.
you might like to think you're self-sufficient but you're not.
you rely on other systems, other taxpayers for infrastructure you use.
you pay what you're made to pay and then what you choose to pay but that doesn't mean you're self-sufficient
life doesn't work that way, society won't either.
