The weak point of your privacy strategy is that the full cycle of interaction "money-goods" or "money-services" is only partially performed in a decentralized peer-to-peer network, and the other part is performed in real life or on the Internet, where, generally speaking, it is much more difficult to protect yourself from deanonymization
Correct. But I don't want to go full privacy. Again, I don't want from the merchant I exchange stuff everyday to know I have an account here on bitcointalk, which makes me an extra income. I am fully aware that I can be de-anonymized in real life, but my goal is to retain part of my personal life private; specifically, this business in this forum.
These are different things. In the case of Monero, not only the content of your payment is hidden from prying eyes, but the very fact of the payment is also hidden. Without a key to read a particular transaction, you won't even be able to know that it actually happened.
This only strengthens my argument, which is that I want financial privacy on the Internet. What you just described is the reason most privacy experts advocate for Monero. It serves better privacy. According to your reasoning, we should neither use Monero because it makes us look suspicious. Why would I want to use a currency which completely hides my financial activity? Isn't that correct?

Yep. We're really talking here about a public ledger that you're trying to misuse by mixing - and in doing so, claim that "it's okay, it's definitely not for dirty illegal business like money laundering."
So, utilizing privacy-respecting tools for bitcoin with limited privacy gained is "bad", "for criminals only", but using monero which is the most completed black-box cryptocurrency to this date is "good", "for every person who wants some privacy". Okay.

BTW, I hope you know that it's entirely possible to receive coins which were used for illicit activity prior X transactions; and that X is arbitrarily marked as "good" and "bad" from mass surveillance corps which analyze the chain and create this "taint" perception.
You are wrong to attribute to my messages a moral coloring in the style of "good" and "bad", I condemn only the misuse of tools. My extensive experience and diverse background in the field of information and physical security allows me to argue that partial and unsystematic efforts to preserve confidentiality are a waste of resources, and it would often be better if they did not exist at all, because the harm is greater than the benefit. It's like building a house with three walls and leaving a huge gaping hole instead of a fourth. You will be protected from idle prying eyes from three sides, but do not be fooled by the illusion that you are safe in such a house.
