"The legitimacy of property rights, however, is rarely questioned." To be fair it's questioned a lot.
In Canada, we made a new Constitution in the 1980's and the 'left party' was going to veto it if we included the specific rights to private property. Trudeau caved and so we don't have constitutionally protected rights to private property in the sense we might want. Though I don't think it's pragmatically much different from most nations.
To be a bit more clear, I was referring to specifically from a conservative, capitalist perspective (which makes sense, since capitalism does sort of require capital to be property.) Libertarian arguments that killing somebody who is taking your property violates the NAP, for example, are rare birds.
