Boiling down this argument: "It's illegal, therefore, it should be illegal". Where adults argue, this is called post hoc, ergo propter hoc: assuming what is to be proved. Since you are, as you say, intimate with the DEA's Young Commission finding, you know that the Judge-Advocate of the DEA ordered the re-scheduling of Marijuana, and that since 1988, the DEA has been, basically, in violation of its own mandated procedures in maintaining marijuana at schedule III. The DEA operates in this questionably legal manner because it is addicted to the civil seizure income from marijuana busts.
Pretty amusing, by the way, that Marinol, which does actually have a clinical track record for killing people due to it's pharmacological properties, is sched. I, while marijuana, which has virtually no clinical record of having ever harmed anyone, is sched III. This is perhaps the most egregeous monument to the blind, illogical stupidity that the drug war produces. On the available scientific evidence, there is insufficient reason to make Marijuana even a schedule I "drug", unless, of course, you count venal, dishonest political gain, and a license to pillage thru civil forfiture.
It was not a judge advocate. It was an Administrative Law Judge, Francis Young. They used to be called "Hearing Examiners" -- federal lawyers who preside over a formal hearing on the record.
Administrative Law Judges have no authority to order squat. As a result of this hearing, this ALG made a recommendation to the head of the DEA. By ignoring the recommendation, the DEA violated nothing.
Marijuana may indeed contain chemicals that are medically beneficial. Smoked marijuana, however, has no accepted medical use in the U.S.
