Do Yoshi-P and dev thinks everyone is RMT?

To Yoshi-P and devs, how did you calculate the amount of gil circulation on each server to come up with ridiculous prices for lands? Did you included all the RMT gil in each server calculation? If that is the case then most likely you believe that the majority of your population are RMT either through buying or selling.

On the patch note I saw this:

Quote:

---

* Purchasing land or housing using gil obtained from RMT (real money trading) or other illicit means is strictily prohibited. Any land or estate hall deemed to have been purchased through such means is subject to seizure.

---

So following the notion that RMT gil contribute to a large part of our game economy to the point that the land prices are absurd, does this mean that our gil are still highly tainted by RMT and anyone can be banned for buying land?
Yes I know that I might be making an exaggerated question but how else can we get words to the devs now that the patch is set in stone?
