without a stable system of government...
False.
Please give an example of a working laissez-faire system in the absence of a stable system of gov, which was not ultimately displaced by a society that enjoyed both. You must internalize the truism that long-term successful business and society require a gov enforcing contracts at the very least. If there is no gov, businesses and individuals will take matters into their own hands, resulting in bloody feuds and far more violence, while in the long run the businesses suffer.
No: you are conflating defensive force, which is every creature's birthright, and "might" in general, which is not.
They are different applications of might. You might thing they are different ethically, but they are not different physically. There is no functional difference between "offensive" and "defensive" might, other than "who started it". Once it starts, violence is violence.
In any case, the ethical difference is irrelevant, because there are no guarantees that your opponents would share your views of right and wrong (incidentally, one of Prof's quotes is a direct indication of that). When they don't, your system collapses. Then conditional power devolves into coercive power (read J.K. Galbraith) and you slug it out. That is why even your society will ultimately be based on "might is functionally right".
"But I will accept any rules that you feel necessary to your freedom. I am free, no matter what rules surround me. If I find them tolerable, I tolerate them; if I find them to obnoxious, I break them. I am free because I know that I alone am morally responsible for everything I do." p63
So, anyone who thinks your existence is an encroachment to their freedom is justified in taking you out, all rules out the window.
"First, what is it you want us to pay taxes for? Tell me what I get and perhaps I'll buy it." p184
Spend some time living abroad. You will convince yourself what you buy in American taxes.
"There is no worse tyranny than to force a man to pay for what he does not want merely because you think it would be good for him." p230
Literally correct, but irrelevant to the discussion. You are not forced to pay taxes because you have the option of opting out at any time. It is your choice to remain a citizen, and you choose to remain because deep inside you know it is worth it to you to do so. The fact that you refuse to admit is one of the inconsistencies of your position.
"You have put your finger on the dilemma of all government and the reason I am an anarchist. The power to tax, once conceded, has no limits; it contains until it destroys." p231
Only if you allow it to expand. Tax cuts that are just a few years old are a counterexample.
"Seems to be a deep instinct in human beings for making everything compulsory that is forbidden." p287
I need the context because it makes no sense as is. Page does not help because I got a different edition.
"At one time kings were anointed by Deity, so the problem was to see to it that Deity chose the right candidate. In this age the myth is 'the will of the people' ... but the problem changes only superficially."
If anything, this is a strike against anarchy.
"I listened to some sessions, then cornered Prof and asked what in Bog's name he was up to? 'Thought you didn't want any government. Have you heard those nuts since you turned them loose?'... But Prof didn't get excited; he went on smiling. 'Manuel, do you really think that mob of retarded children can pass any laws?'"
So the public is a "mob of retarded children"? I guess they cannot be allowed free choice, but need an archon to make decisions for them. You are contradicting yourself.
