A lot of sensitive data is legally required to be kept around for much longer than that (email is up to 15 years if you're a publicly traded company).
Most of the remaining suggestions aren't relevant to ransomware even if they're otherwise mostly fine recommendations. 2FA won't stop ransomware, or data destruction. Redeploying code and reinstalling active directory doesn't restore customer or user databases. Paper files are not accessible when they're needed, are easily damaged or misplaced, and cost a lot to store and index (if you're referring to keeping them as backups then yes you're making a form of the argument of the post just in a very expensive and inconvenient way). Read-only S3 copies are almost certainly falling in the realm of backups... but is also a relatively expensive way to do it for most organizations larger than a start-up.
Offline and offsite backups are the cheapest, most effective tool for keeping copies of your data in your companies possession due to unforeseen circumstances and they protect against a huge number of potential events beyond just ransomware. It's negligent IMO for executive officers of a company to not have invested in a solid, tested, and comprehensive backup solution.

Attacks involving credential stealing almost never involve malware.
