They can just ignore the private UTXO they received from the coinjoin and never combine it with other funds in the address.
Correct. Same address, separate utxos (although it does result in an over-collateralized etf lol)

They cannot ignore something in their wallet it is still in their wallet. UTXO is not something you can use as an excuse simply because it is something that only hardcore Bitcoiners can really understand. And it is only overbloated if it is their real address. Your reply is the reply of ETF lovers. It is quite obvious.

I think the etf operators know what utxos are. And like I said the point still remains, the utxos are separate even if in the same address. Just my thoughts thank you

No. They don't even know that revealing a coinbase address in legacy format is so 15 years ago. They do not even know that it is useless to reveal the wallet address as evidence of ownership. The public key is the standard. They are just pulling our legs for nothing.
