Fixing currency values and killing flippers at the same time.

I want the market to be stable.
all items and builds within reach of all players at all times.

A great way to get there is to remove player ability to "control" the market while keeping it player "driven"

In poe the base currency never got inflated.
Because there were vendors which traded higher value orbs for a small amount of lesser value orbs.

We need this in POE 2
but this should include Exalts, Chaos and Divine orbs.

This way the value of the Divines cannot be inflated to 220+ Exalts. prices of items will still inflated but at least the value of the currency remains static, and the currency flippers ( mostly RMT players) get nuked as well. Their online prices will inflate driving players away from their sales.

Additionally you should make currency more reliably attainable through game play.

IE bring back recopies, Make it drop more often.

Make an exalt recipe like the old Chaos recipe.

Make one for chaos as well.
or make items over item level 65 dismantle into exalt shards.

every single thing written in this post is wrong.

The most egregious?
"In poe the base currency never got inflated.

Really?

"I want the market to be stable.

REALLY?
