I think libertarians are unwise to focus this much on these unlikely scenarios. That’s why libertarianism is always considered in it’s utmost extreme, which makes it appear a lot less likable. And that’s where things get complicated so people can find flaws. If the extreme doesn’t work then certainly we couldn’t move a few steps in that direction. Statists never let the debate get to that level. They never respond to questions like “what about those people who resist being taxed?”. Moderate statists never have to answer for the nasty consequences of extreme statism. And libertarian society are thus always contemplated in these unpleasant examples, while statists keep painting utopia.
