there is a way to make your transactions totally anonymous and highly untraceable, and that is using a coinjoin service, this service is offered by some bitcoin wallets and
WASABI wallet is one of those wallets that offer such feature.
You may want to look at the last pages of the topic you linked here or some of the topics in Wallet software board such as
this one. In short Wasabi wallet team have been acting in a very shady manner and have been working with chain-analysis companies. In other words not only you are not benefiting from CoinJoin but also your privacy in Wasabi is less than using normal wallets.
