This feels like some cartoon villain stereotype of a libertarian. Actual libertarians are big into contracts and contract law. They aren't against agreements, let alone politeness or manners. Heck one of the reasons I eventually became a libertarian (UK sense) myself was due to noticing how unfailingly polite and unassuming they all of were despite often being faced with the most vile hatred.

Consider how nonsensical your comparison really is. The problem in question appears in Russia, a place where the largest official political alternative to Putin is the former Communist party. It's the opposite of a libertarian country. Places like New Hampshire or even relatively non libertarian places like the UK on the other hand, simply can't imagine behaviour like that. It's the whole reason it's an interesting anecdote to begin with.
