Here is my issue with your statement. If you actually read the bottom of the first post on that thread it explains exactly why the list pet's are worth the different amounts of c$. They talk about the exact calculations that you have posted.

Many people ask, "a mid advent is worth 7 09 rares, and an 09 rare is anywhere from 30-45C$. But the mid advent is only listed at 85C$! Shouldn't it be 210-315C$?"
There is a reason why we don't do this.
19C$ = $1 US Dollar
An 09 rare is roughly 30C$. (Just using this as a middle ground, they can be more or less.)
A mid advent is 7 09 rares, so 210C$. ($11 USD - that's already a lot.)
A blue rose dog is worth 7 mid advents, so that would be 1,470C$, or $77 USD. That's a lot of money.
And to take a big jump, a nondog is worth 36 blue roses. That would be 52,920C$, or $2,785 USD.
And finally, a sunjewel is worth 5 nondogs. 264,600C$ or $13,926 USD.
This is why we simply cannot use rarity math like this. A sunjewel right now, at 1840C$, is worth $105 USD which is still a lot of money, but clearly a lot more doable than nearly 14k.
So in reality it doesn't particularly prove that the list is a broken system. They even mention that pet prices and c$ prices are different. You are dealing with real money vs pure pixels. They cannot be a straight across exchange. That would get out of hand fast.
I do not disagree that there are issues with the list, but the c$ list cannot be used in a case against it.
