What if there are no owners? AFAIK, there are protocols for atomic cross-chain trading, and there are dapps that are hosted on the blockchain itself (and are part of the chain). I think dapps have ownership, but I won't be particularly surprised to see if bazaar would be able to try something about consensus-updated codebase without explicit ownership. That could go very wrong, but nonetheless that would be interesting experiment to witness (if anyone would dare, heh). I mean, not for tax evasion purposes, but solely as a "ownerless" software development model.

Node software developers could be at risk, though.
