Very good point Steve. Checkdb is insurance. I just ran into two clients (new) in the same day with some level of corruption in their databases. Neither had been running checkdb against the databases in question. And neither had a corruption free backup (one had no backups since 2008 for the database). Those were the types of things I got to remedy today. The lack of checkdb and lack of backup is a gamble that could cripple an organization - depending on the criticality of data in the database.

Don't take that risk - just not worth it.
