I have this dream of having 4-5 robotic construction workers* capable of tearing down a Single Family home and building a four-plex in its stead overnight.

Then, I just buy houses in High COL areas and start popping them up and moving families in ASAP. What are they gonna do evict working families? Good luck

Then dissolve the underlying corporation before the municipal fines kick in and escape into the night. Render municipal and neighborhood control laws meaningless.

*may not be humanoid, I'm skirting that debate here.
