The material alone is in a quantity beyond what we can reasonably manufacture.

and the material needs to be perfect. All design we have today have cascade failure mode -- any material failure translates to a total catastrophic failure.

and we need some maintenance / decommission plan. How can we decommission this when it fail or need upgrade?
