If Samourai Wallet quite clearly displayed sending coins to 1111111111111111111114oLvT2 in a tx0 transaction, would you consider it "not a bug" and just say that "people are free to do with their money whatever they want"?
In regular wallets, you can create an output that is worth less than the mining fees required to spend it. That is generally allowed. Maybe not in Wasabi land, but in electrum, sparrow, samurai etc, it is allowed. That does not mean it is smart to do it, but it gives you the freedom to do whatever you like with your money.
