I think it’s the only fair compromise. I think we should respect a right to delete. But I don’t think that right to delete should be powerful enough to smother discussion. The person who started the communal thread should not have the power to silence everyone who participates.
I am less concerned with the long term traces we leave. Social interactions are ephemeral (or were, prior to moving them to the Internet) and we are here trying to meet our social needs, not necessarily to Build A Better World. I am all for the things we say naturally expiring and falling out of the record.
What bothers me is how a living conversation can be killed. And in such a way as to make it difficult even to find the people you were just interacting with again, if you don’t happen to remember their account ID.
