> why limit them at all

Because it's a numbers game... the original order itself even acknowledges that the problem is not unique to power banks, but that what makes power banks unique is the amount of increased risk they pose compared to other devices, due to a higher ubiquity of them in general, and of low-quality unsafe ones.

If laptops were catching fire with the same frequency, they'd ban those too, but they're not. They technically can be made just as unsafe as power banks, but they usually aren't, and this directive is based on the frequency of occurrence of a particular type of device, not a general "what if" strategy.

Banning all electronic devices would be extremely unpopular and possibly tank their sales. They're trying to balance safety with convenience at a level that is acceptable to most people.
