If the federal government wants to get you, your basement arsenal will not be much protection.
We spend about as much on our military as the rest of the world put together. If you get to thinking another American Revolution is in order, it's a guarantee you'll be outgunned.

In reality, the line on legal weaponry is arbitrary. We could move it further out and allow people to buy backyard missile launchers. We could recognize the times in which the Second Amendment was written and restrict possession to nothing more advanced than what was available in the late 18th century. But it's wrong to say anything permissible today is sacrosanct.
