The issue is, what happens if you decide you don't want to do business with that entity anymore?
In case of state, the punishment is prison and, resisting that, death. That is the part that libertarians object to, and it doesn't matter whether that entity calls itself "corporation", "mafia" or "government".
With a government -- or a corporation supported by crony capitalism, which is just more government -- a program doesn't have to convince the payers that it's worth paying for. It just has to convince those with the power to take money from others by force to do so and give them some of it.
Not if you believe that governments derive their power from the consent of the governed.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed,
That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.
You may be joking, or pushing a theoretical concept, I have no way of knowing. But coming from eastern Europe, I find this world view of your-life-as-leased-from-government disturbing.
Because you know, the next step to "the government owns all lands" is "government owns all babies, and if they don't like how you raise it, they'll 'take it back'". It's all been here before.
And while you may think you have some great solution, wherein you can be sovereign on your land and somehow not have to personally defend it from nation-state level adversaries, those of us acquainted with the real world know this not to be the case. So, we end up with governments, and those governments are generally pretty shit, but they beat the hell out of the alternative.
If you really want sovereignty, then rather than wasting time with the typical libertarian bullshit, whining about how taxes are violence and so on and so forth, you should instead be putting everything you have behind space exploration. The only practical return to individual sovereignty is the return of sufficient unclaimed land, and the only way for that to happen without a lot of people dying is for us to raise our sights to living other places than Earth.
Do you know how USA itself was formed?
You sound like a somewhat uninspiring, jaded person, but that's your problem. I just don't like people spreading FUD. There's a lot that can be done, here on Earth, to improve liberty and individual freedom. Which is, by the way, not mutually exclusive with supporting space exploration (false dilemma).

My claim is that if you stay on that government's land, you are not in fact choosing not to do business with that entity. Period, nothing more.
Nowhere did I claim that you have to accept the status quo. Nowhere did I claim that nothing can be done to improve liberty or individual freedom. Those are positions that you attributed to me because you aren't arguing against me, you're arguing against a straw man instead of taking the time to understand what I'm telling you.
Space exploration isn't necessary to improve liberty or individual freedom, it's necessary for a return to individual sovereignty without many people dying. You're welcome to improve liberty or individual freedom all you want, either from inside the country or outside of it. What you can't do is live inside of the country but somehow consider yourself above that country's laws because you have an eternal inalienable right to sovereignty. No government recognizes that right, because if they did governments could not function. You can have life, you can have liberty, you can have pursuit of happiness. Sovereignty is not on that list.
