this shows how warped your thinking is
an extension of your argument is that any publican, for example, should not only be allowed to have smoking going on but also to allow customers to freely gun down others in the pub, or hand out bombs to anyone that wants them - because it's their own private property right, so anything goes?
these 'private properties' exist within nation states, which have laws by which we all have to abide. The alternative is literally anarchy.
which might all be very well if you're a gun-toting neanderhal wh9o is happy to live by violence, but most people don't
i suspect you yourself wouldn't last five minutes in the kind of situation you apparently wish for - i suppose you'd try telling a lunatic with a gun to stop trying to threaten you while you show them a video on youtube explaining why they've got it all wrong
