Because we are now in a place where if we want privacy, we are surely trying to hide something.
You do want to hide something-- and that's okay. Privacy is exactly that; hiding information from entities you disapprove of. I don't understand why "trying to hide" is negatively interpreted.
I buy my food in a local store that accepts Bitcoin as a means of payment. As my income comes from the signature campaign, my deposit address is public in this forum, and I don't want the owner of the store to know my virtual identity, I have been using Wasabi for a long time.
For coinjoins, I suggest you look onto JoinMarket. It's decentralized, more flexible with coinjoin sizes, has better fee structure, and of course isn't prone to blacklisting certain outputs. If you can't stand of the terminal, there is a UI now, called
Jam. I haven't tried it yet to see how easy it is to setup.
For example, I am witnessing how supermarkets in my country are raising the prices of some products more than 50% in the last year, and this could not have been done without all the information they've collected thanks to their loyalty cards.
Supermarkets have been raising prices due to inflation. I can't see how the fact that they might have collected personal information about their clients is related.
