That's a fair critique of a bad analogy. But it still misses the point of the collective action problem. Consider a different analogy: you are free to burn as much fuel as you want, and individually it doesn't make much difference. But if everyone collectively takes that same stance, it leads to large negative externalities.
IMO the extreme libertarian view works fine for small groups but does not do a good job of managing collective action problems in large societies when the scope exceeds our psychological bandwidth.
