I'm confused by what you mean
He means a one click installer for a coordinator.
Refer to the BTCPay Server installation video I posted already, you can see the 1 click installer for coordinators there. It's the "coordinator runner" tab.
Still, why would I go through the effort of setting up a coordinator, having zero volume, trying to entice people to my coordinator, all so I can run inferior coinjoins with suffer from address reuse and identifiable outputs, when I can just run JoinMarket instead?
How are JoinMarket coinjoins superior to WabiSabi coinjoins?
That's because the unique codes on the banknotes are not stored forever on a worldwide database every time the banknote changes hands. Bitcoin UTXOs are stored forever on a worldwide database every time that UTXO changes addresses.
UTXO doesn't "change addresses", because UTXO is not money. Bitcoins are, and they are expressed as "value" in the UTXO.
Yeah, I said "Bitcoin UTXOs", there's nothing you needed to clarify about my statement

Each participant has to know the entire transaction in order to produce a valid signature...
You deliberately misunderstood. Obviously participants know the inputs they sign, but they don't de-anonymize each input and approve it according to each participant's "moral score". That must be a brand new feature from Wasabi foundation.
I didn't deliberately misunderstand, your claim was simply wrong:
Secondly, coinjoin participants don't know each other.
You are very clear, I'm telling you that you are WRONG: UTXOs have distinct origins on the blockchain.
Define me fungibility.
Items can be considered fungible if any single unit has the same market value as any other unit without further inquiry about its origin, destination, or unique attributes. If a Bitcoin UTXO was not created from a coinjoin transaction, its origin can be identified with exactness, potentially changing its market value relative to other units.
