What's better? A system where your needs may or may not be met, where there may be somebody holding a gun to your head, or a system where your needs may or may not be met, where there is always somebody holding a gun to your head?
Nobody has ever held a gun to my head.
And nobody's ever juggled knives on a life raft, or smallpox on a front lawn.
The gun is metaphorical, until it's not.
Consider that I send you a bill for releasing oxygen in the air for you to breathe (I've got a garden at home). You would consider this ridiculous and dispose of it. So I send a more strongly worded letter, threatening to kidnap you unless you pay up. Again, you ignore this, or perhaps you believe my threat and take measures to protect yourself. So, not having been paid, I send a man to your house to kidnap you. Being the rational individual you are, you defend yourself from this aggression, with the minimum amount of force necessary. My agent escalates the use of force, as I have given him instructions to kidnap you using whatever means necessary. Eventually, it gets to the point where he is pointing a gun at you. Having no recourse left, you also point your gun at him. Fearing for his life, he kills you.
The only way this is different from taxation is that in my scenario, you would be considered a victim, and if I were instead the state, you would be a criminal. I consider that I provided you a service, for which you never asked, but from which you did indeed benefit. Then, I demanded payment. When payment wasn't received, I initiated the use of force against you.
Do you see the gun yet?
