I do not feel offended. But very nice from you to consider that it could be. Concepts like privacy are nothing personal to me.

And yes might better solutions can come up. But one still has to get around physically. And every physical object can be traced. My point is only, that getting full privacy is a huge amount of work, which no one achieves by the way. And Bitcoin is rather weakening privacy compared to current banking and cash then strengthening it. Physical cash will probably always be the most private payment asset one can use.
