While it is possible to argue about analogies til the end of days, I don't think your analogy quite captures the essence of what is going on with the DMCA. Allow me to present a refinement: There exists one law that says it is only legal to make a right turn on red if you stop and look to the right first. There exists another law that says if you stop on red, you can't look to the right. The net result is that in order to avoid breaking any laws, you can't make a right turn on red. These laws are technically not contradictory, but the end result is to nullify the ability to turn left on red just as the DMCA nullifies the ability to make a copy for any reason, fair use or otherwise.
