I don't disagree with any of them. I disagree that they are
significant
statements, and that they form the basis for a "good, clear, and well

defined" reason for the giant restricted area over DC.

SNIP
The restrictions are set up for very clear, well defined reasons, and

every driver knows it.

1. There are terrorist groups that wish to carry out attacks in the
domestic US.
2. Government buildings in DC are likely to be preferred targets of
such attacks.
3. Small cars are a possible means of delivering a weapon of some
kind.

Which of these three propositions would you disagree with?

None, and DC has in fact restricted traffic flow around the WH and
Capitol buildings significantly.

Of course there is a pragmatic/cost-benefit analysis going on with
anything. You could ban GA inside the ADIZ and the economic effects
would still be minor compared to what would happen if you stopped
allowing large trucks inside DC. While I agree that the freedom to fly
ought to be treated as an absolute, the reality on the ground is that
we are a Special Interest Group that the broader public would sell up
the river in a split second. Like it or not we've got to keep our noses
clean.
