Agreed- but once the human population is reduced by a significant number tubs of 'powdered titanium for 3d laser sintering minifac' will be waiting around for people to find.[1]
Hopefully the people who have minifacs and microfacs will print the item called 'titanium pulverizer' before all of the tubs have been picked clean and depleted.
(repeat statement above for whatever other exotic materials the future microfac will need in its reservoirs- though some of it may be 'pick things up from outside' I think one of those SLS printers actually could produce laser quality optics by just loading it with fine sand)
