Leading an identity-less life will not protect you from having your business intruded upon. It requires a lot of effort and setup, which means a lot of possible trails to leave behind. And if people look into you and see nothing where you should be, that's immediately suspicious. Criminals have been doing it for ages though, by keeping a low profile. You cannot reliably hide from the state, but if you seem insignificant you can go unnoticed for a long time. Low-level dealers in many countries just use WhatsApp, some straight up text and call, despite knowing police could always be listening. If you're selling to a couple dozen people, the police won't bother tracking you down. They have bigger fish to fry. Higher-level dealers engage in much more OPSEC: using fake names, not letting anyone not involved see them, meeting in person etc. This is a consequence of the fact that they are more likely to be noticed.
