Why is this not the solution?

It's not going to make an effective gil sink if the goal is to curb inflation. It could have the opposite effect if the seller is looking to make that gil specifically so they can spend it on items that other players are selling. A 150 million gil transaction might see 30 million inactive gil removed from the game at the same time 120 million previously inactive but now active gil enters it.

Expensive gil sinks tend to remove gil that's not in active circulation and so don't impact inflation in the player economy. Look at what has happened in the last 6 months. Players asked for more gil sinks so SE added gil sink mounts for 25 million and 50 million. Did that have a positive impact on inflation? Of course not. It only hit gil that the buyers were not using and had no plans to use.

I also see almost no one with these mounts, and I personally know at least one billionaire who has said he's not spending his money on it regardless of how much he has. The issue here isn't that big ticket gil sinks don't work, the issue here is that they didn't offer anything someone wanted.

What was SE's next response? To announce that teleport fees would be getting adjusted and Aetheryte tickets would no longer offset all teleport costs to every location. Now that absolutely will impact inflation because it's hitting gil that every player is actively using, not gil the rich have stashed away on some retainer.

Which will absolutely function as a gil sink, yes. What it won't do is remove the incentive for RMT bots to buy and flip houses, which is the other benefit of this idea.

Probably the biggest cause of inflation in the game is the gil cap. There's no reason for gil cap to be 999,999,999 per character/retainer when the largest game controlled purchase price is only 50,000,000. That's an insane amount of gil that can be accumulated compared to the typical gil reward for game play (usually between 500 and 8k gil).

If SE is really concerned about inflation in the player economy, they need to remove the ability to store gil on retainers and slash the gil cap to 100 million. That's high enough for a player to comfortably accumulate what they need to get the most expensive game purchases while reducing the gap between the rich players and poor players considerably. The poor player will have more buying power because what they have will be closer to what the richest players have. The rich players will still have more of the fun items and be more effective at making gil when it's time to replace what they spend but prices on player to player transactions would be reduced considerably because no one would have as much to spend.

There will absolutely be a response to this that defeats the purpose. You have 10B gil spread across yourself and nine retainers when this is implemented? Good thing you can make alts, which also have nine retainers each.

And assuming they can't do that, they'll just start spending the gil, which will cause inflation.
