Except the reality is few FCs have 200+ active unique members. In most cases those members don't benefit from the FC owning a house because officers tend to rigidly restrict house decorating privileges and rarely spend any gil made from gardening, workshops and company credits on the members. Access to purchasing FC chambers mean nothing when players can easily buy an apartment with or without FC membership.
You're dramatically inflating the potential impact when there just aren't that many multiple house owners out there, grandfathered or not, and most worlds don't even have 23,000 active players.
Do yourself and everyone else a favor. Turn your crusade toward something that actually would make a dramatic and positive impact on housing for the community - expansion of the instanced housing system - instead of on a dead cause that would only benefit a handful of players per server.
