>depends on whose hands it's in
Mechanosynthesis is most productive at extremely cold temperatures because positioning errors go down. Less errors means less waste. Because of the need to keep things really cold, big printing factories are much more economical and productivw than home printers. There are economies of scale in cooling.
>bombs don't need to be visible or knowingly smuggled
And how is this different than conventional explosives? Why wouldn't they need to be smuggled? How do you get the bomb to the target? Nanotech isn't magic.
