Hard pass.
For one, the idea is absurd and not resolve any present issue.
No point to alter current house ward framework as it has been function as it supposed to be in an environment where supply is unable to meet demand.
Your pointless crusade on grandfathered ownership and house relocate doesn't resolve the supply and demand issue.
It is only worsen the problem and creating unnecessary drama

You can just stop until we see the impact of following 3 factors in 6.0:

1. Ishgard housing ward release (more plots)
2. Island Sanctuary (possible instance with farming to make people happy with apartment able to gardening)
3. Open of Oceanic datacenters that has potential to further free up plots because people from Oceanic will likely migrate
