You're right. But synthesizing enough material to be relevant to an industrial effort is a leap of engineering so large as to be beyond our capacity to imagine its possibility.

With the way that resource allocation seems to be bound by presently, if there was a war, and one/some group could some how get the resources to scale up such processes if they could seriously convince the war planners of its "super weapon" capabilities, I could see it happening even if it took a couple years to get a working prototype at scale (depending on its ability to not compete sufficiently with other resources for war to not purse such project at all). And seeing that humans haven't came up with the abilities to avoid war completely, it's only a matter of time (which may be a lot for an individual humans lifespan).
