Even from a pure individual pragmatism perspective
this advice looks incomplete.
If you 'just' pay the ransom I guarantee you'll be flagged as a soft target and it will happen again sooner rather than later. For most people and organisations that aren't high profile security is about being more diligent than the mass of other potential targets out there.
If you're secure enough not to get hit or get hit but can detect early, segregate data and restore from good backups then you're unlikely to be specially targeted again in the short term. Any organisation, small or large, that gets hit, quietly pays up and considers that that's the end of the matter will definitely find a different but eerily similar looking set of Danes on their doorstep again soon.
If you get hit and have no alternative to paying then pay but for God's sake put some money and time into planning the layered defences you should have had in place beforehand. If you consider that you can't afford that because you just spent the money on a ransom then your judgement is probably not good enough to run a business that anyone should deal with.
