Clearly you have never heard a system administrator utter the phrase: "But, they were only logfiles. We needed to clear some space." coupled with "We don't backup logs."
With a cold backup you *know* that you can get the database back in a working state, even if some sysadmin has gone nuts and earned themselves a place in a large body of water encased in chicken wire with some heavy weights for company.
With a hot backup you also *know* that you can get the database back. There is no difference. Now if you are going to suggest that after sysadmins delete part or all of a backup to save space then you have problems, well obviously I agree. The same however surely applies to cold backups as well.
