Not reusing the same adresses is considered "mixing"??? Not at all, this is just compartimenting UTXOs.
"Unhosted wallet providers" there's no such thing as a unhosted wallet. All the wallets already exist on the network, no one owns a wallet like you would with a bank account... you can't host a wallet, you pick one up from the network and you use it, thats all.
This is just an attack on privacy, fuck I hate them!
