As for your second point, I believe that any animal can be kept alive in captivity, it's just we don't have the experience or knowledge to care for some (or at least didn't in some cases and do now).
It was considered difficult/impossible to keep Sumatran rhino alive I believe, but now that Cincinnati has the experience and the knowledge they seem to have done a decent job, even having 3 calves before losing their breeding female Emi.
Fantasies apart..
Sumatran Rhinos have been kept alive sucessfully for long periods of time in the past by London Zoo(1800's) Copenhagen Zoo and Port Lympne- long before Cincinnati managed to. And at Cincinnati the male Ipuh nearly starved to death before they learned how to keep them properly( the diet) whereas this was, curiously, a problem which the other zoos like London, Copenhagen and Port Lympne never appeared to have! The problem was breeding them, which only Cincinnati successfully achieved but then only Cincinnati had a potential pair of suitable breeding animals.(London probably never tried, both Port Lympne's females were unfit/too old, Copenhagen could never obtain a male for their female).
Whether Cincinnati can still continue to build on their breeding success with this species, after the setback of Emi's death, remains to be seen.
