Depends on where you're going. For Northern VA (Herndon, Reston, etc.), yes, IAD is the preferred airport. Even if leaving from elsewhere in VA in the morning, driving to IAD on the dedicated two lanes of 267 is easier and faster to get to than being stuck in rush hour morning traffic going to DCA.
It all depends. You just seem to discount all other and different perspectives from yours (it sure does make life easier to put on the blinders and take a myopic stance). Luckily, DoT and others do not agree with you - as they know and understand how the world works. If they did, then HA would not have the original slot it got. But, DoT saw what you fail to see: that it should be awarded where there is the greatest gain to the US economy (and thus US gov't revenues).
