Two problems with your comments on the reserves. First, although your cost & deployment figures are OK for simple organizations like truck companies or quartermaster units, combat arms units need extensive training prior to employment. Single functional combat arms units like ADA or GS artillery are next up on the scale. Reserve Component organizations designed to conduct combined arms combat maneuver warfare ned lots & lots of training to get to a level of equivalence with active forces.
Second, the guys in the guard & reserves are in there for a reason. If they wanted to be full time, they'd be in the Regular Army. They don't mind being called up for the occasional long term deployment or for a national emergency, but back to back to back routine deployments is not what they bargained for
I agree with your second point, but will contest your first. My old National Guard infantry brigade (3rd of the 29th) trained at JRTC on a regular basis and consistently ranked in the middle or (usually) top third of the units that went there. This included mostly active army units.
The "need for extensive additional training prior to deployment" has been a constant argument by active army advocates against the Guard. Usually, this is followed by a request to cut combat arms units in the Guard and increase them in the active Army.
