You aren't configuring anything or doing anything that needs access to the file system.
You are simply interacting with documents and online systems/applications that you can do the same as on a laptop. Add the greater mobility and the iPad pro really is a better device for most people.
However, as another commenter mentioned, these individuals who SHOULD really benefit from using an iPad primarily also are the group that struggle greatly with the changes to their overall workflow (see Who Moved My Cheese).
IMO so few people know how to code because we have been abstracting it for years, not because its tough to do or anything like that. Plenty of things people do are just as challenging as coding. You just need exposure to coding is all, its easy to write bash or python. Anyone could do it in a week. Hard to get that exposure when a company decides it won't be possible for you, and its a slap in the face considering these features are there in the device but you have to jailbreak the damn thing and violate your warranty to get at them.
The company decided it was not possible using a specific product. You decided to use a product where it was not possible.
I bought the device, why shouldn't I?
You can do all the basic copy/cut/paste ops and create whatever folder structure you want. Don't expect to edit system files though. People spend lots of time looking for vulnerabilities to achieve that.
In contrast, Android also doesn't let you access the root file system, but the user folder is yours to do whatever the hell you want with, and if you want to give your audiobook or music app to your folder of mp3 files that you've collected over the years, you can.
