Which is why the point she/he made is full of holes. Getting rid of vehicles and getting rid of guns would not have equal consequences. I would guess that ardent extremists on the gun side would somehow try to make the argument it is, but I don't think any rationally thinking person would seriously make that argument. Considering guns have been around longer the vehicles and it was not until the invension of the automobile that economies of countries whos populous owned them exploaded. While the ownership of firearms has not had anything like that effect.
Firearms have had a far more profound effect than vehicles.
Before firearms became common, egalitarian democracy hardly existed. Not long after, it started becoming very commonplace indeed.
Why? Because it changed the force equation and made it possible for the common peasant to kill the armored knight (with a lifetime of training in arms behind him) with only a few days of training.
Similarly, the 2A is not merely about guns; it is about The People sharing in the sovereign power of Force that oppressive governments reserve to themselves.
Let's ask George, Tom and Rick what they think...
"
Firearms stand next in importance to the constitution itself. They are the American people's liberty teeth and keystone under independence … from the hour the Pilgrims landed to the present day, events, occurences and tendencies prove that to ensure peace security and happiness, the rifle and pistol are equally indispensable …
the very atmosphere of firearms anywhere restrains evil interference — they deserve a place of honor with all that's good."
George Washington
First President of the United States

"The supposed quietude of a good man allures the ruffian; while on the other hand arms, like laws, discourage and keep the invader and plunderer in awe, and preserve order in the world as property. The same balance would be preserved were all the world destitute of arms, for all would be alike; but since some will not, others dare not lay them aside …
Horrid mischief would ensue were the law-abiding deprived of the use of them."
Thomas Paine

"To preserve liberty, it is essential that the whole body of the people always possess arms and be taught alike, especially when young, how to use them."
Richard Henry Lee
American Statesman, 1788
