OP has not a shred of hard evidence to prove any of their accusations other than "everyone knows". Bravo.

The cutest aspect of OPs rant is that he thinks his new proposed requirements are beyond the efforts and capabilities of those who buy multiple houses or run a fleet of submarines. Your shortlist of conditions are based on what you are capable of, which is not much. It will only serve to punish more innocent players while briefly inconveniencing the ones you hate.

This shows just how narrow of an understanding you have about the world multi-house owners live in and what kind of efforts are involved in creating and maintaining one such empire.
