I completely agree. I think going anon is a good idea. But the issue that comes with that is, will anon look shady in the B2B landscape.
It's not about being 'shady' only, more like having a reciprocal interest in transparency. It happens I have contacts with some "big business" peers, it's not just B2B. Most of the time, they even pull in trusted certified third parties and sometimes they even publish their contracts on appropriate media for public scrutiny.
Being transparent and fully traceable is often seen by both as a way to protect themselves in case a future hiccup occurs not only between themselves but also WRT other peers (e.g. the shipping company physically delivering the goods). Believe it or not, they are very often not concerned about this whole privacy thing.
Note: generate new addresses. As long as you keep your privkey secure, you're still behind a cryptographic-strength wall
at no cost. Eventually consider stealth addresses.
