Article 1 section 8, sixth enumerated power includes a post office and post roads. The fact that you are unaware of this makes me wonder if you have even bothered to square your philosophy with the constitution.
Further, states funding the federal government solves nothing. ALL forms of government must get their funding from the people at some point. If the states fund the feds then where do they get the money? Of course it originates from the people. I ask again, HOW do you intend to fund the government? So far you have avoided both this question and clarifying how you view the constitution. You have not mentioned what you think the government should even do in the first place let alone how you are going to fund this system while being completely against taxes.
You chide him for not knowing about post roads in Article 1, Section 8, then ask how he (or any other libertarian) would go about funding legitimate federal functions?
Lawful imposts, duties and excises, per Article 1, Section 8....That's how.
I have not chided him for anything. I was asking direct questions on how he would intend to fund the government without anything that would be essentially a required tax. You mention ‘lawful imposts, duties and excises’ (of course leaving off the FIRST part of that statement ‘The Congress shall have Power To lay and collect Taxes’

but again, this is not much of a real explanation. Income taxes are lawful as well by the way and yet there is a distinct derision against such (or any tax it seems).
I fail to see the difference in a tax, or imposts, duties and excises. All are enforced in the same manner that a tax is enforced and all are extremely unlikely to bring in enough to fund the basic requirements of government. Are we only going to target ‘tax’ on goods that leave or enter this nation? Do you think that will work in today’s global economy? If so, then am I remiss in thinking that you wish to disband NAFTA and the practices that go along with that? See, there is a LOT more to this conversation.
I consider myself a libertarian and I agree that the government has gotten WAY out of control but there are still things that the government must do. Most are outlined in the constitution and most could have been funded 200 years ago through what you described but this world is not the same as it was. The liberals and conservatives seem to have taken that to mean the government needs to grow in power, size and scope. I disagree but that does not mean there are not some basic changes. For instance, a navy is called for in the Constitution but a Navy today is NOT the same force that it used to be. It requires a LOT more resources to maintain an effective navy than it did back then (not taking into account that an air force is even more important now).
I don’t have a particular aversion to an income tax though what we currently have is nothing even remotely like an actual income tax.
Essentially, I am looking for some deeper conversation on this and it seems I am getting resistance and that somewhat surprises me. I am confused about the reluctance to get into a real discussion about what the other posters that consider themselves libertarians actually think here.
