Those rights are very flimsy actually. The government can seize your house, your car, and your money anytime. Hardly a monopoly when a third party can break it at will.
Sure. That’s how rights work. It’s why we need to keep on fighting for them when necessary.
That the state which grants you your right can take them away doesn't make them flimsy.
And it's certainly more than "hardly" a monopoly. If the government gives a certain company right to operate on train track infrastructure but denies the same to every other company, then does that first company hardly have a monopoly?
