Imagine A libertarian exercised his freedom by not masking on the subway and due to that gave Covid to an older passenger who later died, depriving him of right to life. How could we ever have seen that different individuals’ rights can conflict?! Impossible! Couldn’t be imagined! it’s morally inexcusable. How impolite of peoples rights to not all be compatible 100% of the time. Life shouldn’t be nuanced like that! It’s inexcusable. Wait that’s awkward, apparently that’s one of the core tenets of libertarianism alongside the core logic that giving an inch is the same as giving a light year in terms of principles. I don’t take libertarianism seriously because of blatant things like that usually being core to proponents. I struggle to even believe they believe there arguments.
