To be clear, we're talking about doing this in advance of something bad like that happening. Legal damages like that mostly attach to a sort of "snapshot state" — whoever held each thing at the time that the damages happened. So you can't get away from the debt by throwing away the condo. But if you already had thrown away the condo before the building collapsed, I don't think it'd be your responsibility. (Compare/contrast: what if, instead of burning the deed before the collapse, you instead transferred the deed to another condo owner? Or, say, to the HOA itself? Both of those are just as simple in the crypto case as "throwing away" the token is. In the real world, transfers like that need to be witnessed under contract law. But in the crypto world, most tokens don't have sophisticated logic for recipient-agreement-gating transfers like that. You can send most kinds of tokens to people whether they want them or not.)
