You confuse ending ineffective enforcement with "availability." All of those drugs are already available to their target markets. Ecstacy, for example, is a popular club drug because it is easier to get, and conceal the use of, than alcohol. Better to lower the drinking age.
You also make the mistake of thinking that legalizing drugs would lead to an expansion of the market for hard drugs. Heroin and other more dangerous drugs have a self-limiting market. Heroin was not widely used before the Drug War, and it has not become less widely used. Similarly LSD is easy to make, easy to hide, almost impossible to interdict, and yet, ourside of the Phish tour, not widely used. Crank is a biker/redneck drug, impossible to stop, but it doesn't find much use outside that culture.
In general, you are confusing stated intentions with actual effects. Tell me which government program actually does what it says:
EPA?
The Civil Rights Commission?
OSHA?
Dept. of Ed.?
Etc. About the only competent function of the FedGov is the military, and even there you would have to make an exception for domestic projects of the Corps of Engineers, which is one of the biggest blobs of pork fat in the budget.
So when I say end the EPA, I don't mean pollute everything. Who would even accuse me of being anti-education for wanting to end the Dept. of Ed.? However, you find it very easy to call me "pro drug" when I want to get rid of $70B in spending that doesn't do what it says it should do.
The Drug War is just like every other failed government program. And Patriot II will become a dangerous tool in the hands of a less good man than Dubya.
