You just made the argument that the government can tell me what I must use my property for, and that I can't set rules for entry, because your right to park supersedes my right to my property.
Not true. You've been told that we the people have a right to keep arms in vehicles, and you can't infringe on our right.
When the government violates the rights of industry owners in the name of the worker, we have socialism.
When the government allows industry owners to violate the gun rights of employees in the guise of 'safety', we'll have socialism.
I'm not infringing on your right to carry, you can keep your guns in your vehicle, but you can't park your vehicle with guns in my parking lot. You wish to park your vehicle in my property, against my wishes, and thus you seek to violate MY rights, and you want ti use government to facilitate the violation of my individual property rights.
You are creating some absurd Constitutional right to convenient parking.
It doesn't exist.
It's the same argument that liberals use to promote the right to kill the unborn, a non-existent right (to park conveniently/privacy) used to violate an unalienable right (to property/life).
