Why is this not the solution?

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 might get it for less. And you have zero chance of the placard taking your gil and running off.

Flipping only exists in the first place because SE tried to pretend that supply and demand don't affect prices on a limited resource. This would introduce that factor back in. Flipping isn't going to die, but its going to severely drop off.

Because 100mil off a flipper is static - that's the price and it won't change, AND flipping is a nearly solid enterprise within the game, with ways to ensure you get your house as there are dedicated discords for this, with active communities (I'm sure someone who is active in such communities will come in here to pipe up). Whereas having the "potential" to get the house for "less than... or greater than" 100mil is not a solid opportunity, with plenty of chances for failure.

This idea is, honestly, worse than the lottery system we're about to get.

You apparently don't know a ton of flippers. Most of them put the house out there and take bids for a few days or a week and then sell to the highest one. The only time you get it for a static price is if you offer them more than what they imagined they could possibly get for it or if they're strongly motivated to get rid of it, such as leaving the game or the server. And yes, I know this because I'm in one of the Discords where it happens. Frankly, the fact that flipping is a static price is a myth, and I'm not quite sure where it came from, but it has absolutely zero basis in fact.

There is a lot to criticize about this system, and its far from perfect, but to claim it encourages or even won't discourage flipping is just flat out wrong. Flipping only exists because prices are far less than what someone is willing to pay for the house. This explicitly changes it so that the house will go for what someone is willing to pay for it.
