I think there are many rights violated as a result of lobbying. Access to basic healthcare is curtailed in the name of profit, largely as a result of the power of lobbyists. I think this has a very large functional effect on the freedom of everyday people. Even if they have reasonable means they may be essentially forced to continue working for an employer who provides health insurance or risk personal financial ruin if poor health befalls them.

The power exerted by 3 letter agencies is greater than any other western nation in my opinion. They are massively bloated with excess capital and power, and it has allowed them to indefinitely extend their jurisdiction until it significantly overlaps with people's right to privacy.

That said I doubt either of these issues would be much improved without guns. An armed population seems mostly incidental. One downside of focusing on armed resistance, however, is that you can easily delude yourself into thinking you're better protected from tyranny, when in actuality the war is already being lost in courtrooms and political backrooms without a shot being fired.
