It's not like you just create an alt and buy a house. The founder needs to at least have done the dungeons and story to join a GC and get to Lv 25. Then of course find 3 others, found the FC, and then get it to rank 6. Plus raise millions of gil. After all that, I say they have earned the house.

SE also said the housing servers weren't ready to support lots of houses at first, so the high prices were also to keep the total numbers low, regardless of who might buy them.
