Power is not a zero-sum game. Some restrictions of power/rights enable more power/freedom than they take away. This is obvious. The restriction (or convention, but I think the point still stands) to drive on a particular side of the road allows us to do so much more than if we did not have the restriction, our net 'power' has increased. Similarly in many other cases.

I think that many of your examples are good ones and that arbitrary restrictions of freedom are wrong, but restrictions on the possession of weapons by the general public is not arbitrary and if you want to make a utilitarian case you are going to need to talk about the pros and cons of gun control itself not more generally about freedom and rights.
