'If a mixed economy, with some part of the economy controlled by the state and others by individuals, is bad, then shouldn't we go communist?'

why not go full individual? why does the government need to get involved in the economy, what does it produce that business doesn't? you're still missing the box. there is nothing government does that we cannot do for ourselves.

kudos to you for the research - but you're only talking about income tax there - what about all of the other taxes i mentioned in the op?

again, an alternative view is that we keep all of our own money, and take care of all of our own problems, as families and neighbourhoods. no need for the expensive apparatus of a huge central and local government to plan and decide and get a wage whilst doing so, if a road needs to be built or someone needs an operation we pay for it ourselves, like how we used to do until about 200 years ago.

i urge you to check out some other thinkers and speakers on the topic of libertarianism/ stateless society - tom woods and larken rose come to mind, as well as etienne de la boetie. peace.
