You can't sign up pets (they'd never pass the income requirements) - but I know what you mean! And yes I can see your point now that people who otherwise never set foot on a QF plane could end up with status under the ASA scheme. At least with JQ you are buying the base fare to start with.
As we all saw from the QF annual reports, Qantas loyalty made $315 million. That's profit. That profit comes at the expense of the 10.8 million members... whether businesses buy points (and pass the cost on to QFF members), or whether QF loyalty buy a toaster for $5 but charge $50 worth of points to redeem that toaster.
Thankfully I suppose this is where FF ignorance is actually a good thing (for us). Many members probably have no idea what 'oneworld' is all about. They don't know you can redeem your sign-up bonuses on partners like CX or JL. That's probably a good thing, more seats left for those who know otherwise
