A city could be destroyed by a nuclear bomb at any time - that doesn't mean components of a system shouldn't be reasonably durable. Often it's impractical or unnecessary to have multiple servers for a proof-of-concept, a staging/test server, etc., yet it would be nice to not have to start from scratch, or to deal with backups, just because the database is so fragile. Basically, having a non-durable system forces you to take unnecessary precautions on non-critical systems because of the higher likelihood of failure and lost time investment.
