Why is this not the solution?

[ItMe]

So if someone is willing to pay a flipper over 50M for it, lets say 100M, why wouldn't they just bid on a house for up to 100M instead?

They could, and they'd be outbid.
Not everyone likes paying flippers, and not just because it's against the ToS.




Another downside to the bidding idea is that you can't just play the game for whatever you think is fun (something the devs try to enable).

If you're in this game for MSQ and running stuff with friends you're no longer getting the gil to buy a house anymore. That's pocket change to what you're gonna be going up against.

If you're a raider, sorry.

Spend your time RPing? Glamour fiend? Those activities don't make Gil hand over fist so you're SoL.

Locking houses behind a bidding wall only serves certain playstyles (mainly people that are always playing the market board, and crafters/gatherers).
So by locking housing behind a bidding war you're also low key locking it behind having to engage in certain content, which is a mega bummer to put it lightly.
(or players could engage with RMT and hoooooo boy let's not do anything to encourage that).
