Earlier quoted context omitted.
It's not even slightly divorced from the real world. If you don't "pay your taxes" they will eventually send men with guns to confiscate your property and/or arrest you. And if you try to protect yourself, said "men with guns" will fucking shoot you dead. That is reality. And it's absolutely horrifying.
But it is nothing compared to the reality without taxes, where ANYONE (who can afford more men with guns than you can) can come and shoot you dead right away and take your property, not even giving you a chance to pay taxes (or vote) first.
Technology has come a long way in the last 1000 or so years. I suspect that there are new solutions to the problem that you describe. But they don't get explored because the State has a monopoly on violence and is very resistant to change.
Most of the time that's a good thing as it means that things get screwed up only very slowly. But it also tends to prevent things from getting better, too. Only the most egregious problems get solved.
