So, with everyone in the country now knowing where there will be supplies, how do these underground folks keep them out over the long term?

Men with rifles, a backhoe and a D8 will eventually prevail.

It'll depend on how long their hired security hangs around and does the job they were paid (no past tense) to do.

That'll depend on how quickly the hired security figures out that they, not their protectees, have the guns ... and just how much value they're sitting on.

I think that'll happen pretty quickly.
