Maybe, but Hamilton, Madison, and Wilson thought otherwise. And again, how is it that we coincidentally have ONLY those rites mentioned in the BOR? Can that be coincidence? I definitely have sympathy with your argument -- with the BOR we at least get a few rites, or parts of a few rites, and without it, the enumeration would have still been lost -- but I don't think you can be that sure of it. I certainly am not sure either way, but it is interesting to wonder about.
The additional amendments added a measure of difficutly in revoking those rights once the concept of enumeration was lost. The concept of enumeration was going to be ingored, BoR or no BoR.
Please note they didn't prevent those rights from being lost, they merely slowed down the process. Once the concept of enumeration was abandoned, it was only a matter of time.
As an analogy, think of a sea wall surrounding a city. The sea wall is the concept of enumeration. The city is the Constitution. Within the city, the most valuable buildings (rights found in the BoR) are placed behind additional walls (the amendments found in the BoR). Once the sea wall is breached, water (excessive government) is going to flood everything within the city. The additional smaller sea walls hold the water back for a short time, but they will ulitmately fail once water gets to them.
I suppose the author's argument is that the people spent all their time tending to the smaller sea walls than tending to the large one that surrounds the city.
I contend that the larger sea wall was doomed from the start, due to the rising tides of socialism and the forces of domination that are inherent to human nature.
I hate to be the one to break it to you, but we don't have any of the rights in the BOR anymore.
