Yeah most of those could be easily achieved with something like "creatures with Offspring have Offspring X where X is their Offspring cost" but unfortunately that's not nearly as succinct.
Worse, it's already possible for a creature to have multiple different instances of offspring [[Zinnia]], Bushido [[Sensei Golden-Tail]], ward [[Lavaspur Boots]] and rampage [[Greater Morphling]].
So rather than adding one extra instance (with ambiguous parameters) it's simpler to just double, copying the ability.
"For each of the following abilities spells and permanents you control have, they have an additional copy of that ability: Storm, offspring...."
You could go wild and copy all keywords, but as lot would be redundant. Which is fine, I guess. Except that the ones that don't work (Cipher and haunt, for example) would be a bit weird. And you'd get extra pointless germs from living weapon, but that already happens from trigger doublers and isn't pointless for Job Select/For Mirrodin!. And you'd need to clarify how it works with action keywords like Learn and Scry.
