Not the same thing by any stretch of the imagination.
I was referring to the right to travel. In the same sense, I have the right to travel to Europe this summer, but if I don't have the money to make the trip, I can't exercise that right, can I?
Even assuming arguendo the Second Amendment is an individual right applicable to the states (courts are still murky on this one - don't challenge me on this, you will lose as I will post the case law), the exercise of all Constitutional rights is subject to reasonable limits. Your right to free speech is subject to time and place restrictions, for example. The Fourth Amendment simply does not apply at the U.S. border or the functional equivalent thereof, even to your laptop, for another example.
So it is with the Second Amendment. Insane people do not have the right to keep and bear arms at all, nor do children, nor do felons. The reductio ad absurdum of your argument that the Second Amendment is untrammelled would be to claim that it gives you the right to bear a nuclear device, a howitzer, a tank, a machine gun or a grenade launcher. After all, the government has all of these and if you accept the argument that the purpose of the Second Amendment is to give the people the right of rebellion, then why shouldn't you?
