What I just posted was a theory. But my whole point is, whether you set up your own (expensive) chip foundry or else have a company do it for you, the whole idea of my theory is that the conditions can be replicated to make the appropriate chips, processors, or whatever parts you need replicated at that time.

Your theory boils down to, "Anything made once can be made again.". Which is self-evidently true, but not necessarily useful.

A bigger problem than clean room conditions, yadda, yadda, yadda, is the toxic chemicals involved in chip manufacturing (e.g. hydroflouric acid).

A smaller problem (for a billionaire) is simple economies of scale. The cost to tool up to make a chip is huge. In the millions, generally. If you're only making 1000 copies of the chip, or that is the total demand, then congratulations. You've just produced chips which cost several thousand dollars each.
