In my case I believe like you do that cloning could potentially trivialize the perception of species extinctions by the public and by implication the entire crisis of biodiversity loss. If species can be "resurrected" so easily it takes away the value of conserving them, I agree.
However, I also think that cloning extinct species is just a colossal (and insane in my opinion) waste of much needed money that could be allocated to attempts to conserve species that are still extant and at a critical time when we can ill afford to be wasting these resources.
I think the key phrase here is "'resurrected' so easily". I don't think cloning of any animal, at least not to the extent where a brand new population can be established, will ever be an easy process, at least not in our lifetimes. I think what is much more likely is the 'resurrection' of a handful of individuals, which will then need to be kept in zoos or another type of breeding center where the focus will be on natural breeding. Maybe some more animals will be cloned to add to the population over time but I think what we will end up with is a number of now extinct in the wild species brought back via cloning technology but only in small numbers and whose continued survival will rely on natural captive breeding. Afterall, if they can't breed naturally, they'll never be viable in the wild.
While I agree with the cost of cloning being high and in many cases probably futile, I don't think they're really taking much money away from conservation programs. I don't imagine the funds for these two types of projects often come from the same sources, and while the funding from the former could be reallocated to the latter, if all cloning technology projects were ceased I doubt that would be what happens anyhow. I also fail to see it as a waste of time or resources when the fact remains that an extinct animal had been cloned over a decade ago now, it just did not survive long-term. The technology is here, and getting closer everyday, and the science is anything but fiction. I'm not sure if we'll be seeing the likes of the Thylacine, Passenger Pigeon, or other more historically extinct species anytime soon, if at all but I do think cloning as a means to potentially boost numbers of animals like the the Northern White Rhinoceros, Javan Rhinoceros, Giant Sable Antelope, South China Tiger, and Asiatic Cheetah is something we will see as a last ditch option sooner rather than later. As I said earlier, all eyes on San Diego.
