Tell me why people send coins to burn addresses such as 1111111111111111111114oLvT2? Tell me why people send coin to the genesis block public key? Tell me why people burn coins with OP_RETURN outputs? Tell me why people trade their bitcoin for worthless shitcoins? Tell me why anybody would throw a coin in a well to "make a wish"? Tell me why people throw over a million euros in to the Trevi Fountain each year?

As I've already explained to you, Samourai quite clearly displays the change output prior to Tx0 being signed. If a user does not want to create that change output, then they are free to modify the transaction. People are also free to do with their money whatever they want. They do not need permission from you, Wasabi, or any other pro-censorship third party to do so.
