You always have to weigh costs and benefits as a part of your decision process (repeat, part of). When I worked in a restaurant, I was in favor of laws that required me to wash my hands after using the restroom, even though it trampled on my right to have dirty hands. If you really want, I can name a dozen other ways I have accepted that the trampling of my rights was appropriate. Among them, I might even find one or two where you would agree. For example, do you think butchers should have the right to sell contaminated meat?
Now, with respect to gun laws, the harms to others tend to be less frequent, and the benefits to the individual somewhat larger, than having dirty hands. So, I think there's a real case to be made for some level of individuals carrying guns and discussion over when it's best to be able to carry. However, that case is not going to be made by saying "It's my right" or using loaded language like "trampled".
Perhaps. But the case to restrict it is not made based on "what ifs" and "maybes".
