A famous billionaire spent 42 billion to purchase twitter. I can think of more exciting ways to spend that much. I would want to build a bondage fantasy land. Start with an enormous piece of land. There would be a prison (both modern and from various time periods) a castle with dungeon, an English manor with heavy four post beds in every room and a stable, and lots of outdoor venues. Of course we would need staffs including metal and wood workers, leather workers, costume designers, tailors and sewers and of course dommes and subs. What would you add? How would it look and work?
