Good question. For nostr:npub1jluy3twvf338v6zlujzzdhjkzjy8ezj34ksydr8vw8a6jwp89ygshpp2kq nodes, you can totally use a "burner" email address, and a VPN, so we (or anyone else) would have no feasible way to connect your real-life identity with your node. And we've engineered what I believe is the first "disposable node" setup, where you can start a node, open channel(s), send sats around, and then fully delete the node a few minutes later. (Note: We have safety code which won't let you delete the node if you still have sats or open channels!)
