OP means every individual animal brought to other planets—not every single animal in existence.
Every policy we can take has some knock-on effect, however small, on a vast array of different people (and animals). We can’t just ignore some impacts by fiat. The justification for narrowing our scope and focusing only on some subset is typically because either some effects don’t matter morally (e.g. wild animals don’t matter, only humans) or because they are very small (most people will benefit and only a few will lose out). But OP rejects both these strategies, and takes a hard deontologic/rawlsian line, so even if he is only intending to discuss the impacts on some animals, logically he should apply the same to everyone—with paralysis the result.
The implications of this is only that we find it preferable not to terraform—which isn’t paralysis—just opposition to that particular policy.
No, because the world is so big and complicated that every single decision you make will make some animal worse off, and slightly change which animals will be born in the future, some of whom will suffer. OP is applying a standard here so demanding that, if applied generally, no action could pass muster.
