I think you are wrong about that!
I don't want to talk about making the stuff on an open forum, but do a bit of research at any decent public or university library (don't check out the books or use the internet, the FBI is watching and you'll end up as a terror suspect even if you aren't even vaguely close to being such). The precursors are, more than likely, avilable to you in very large quantities within 50 miles of your residence. Even that Jap terrorist group (forgot the name) didn't have any problem making quantities of the stuff and Japan is much more restrictive than we are.
