You might if it were drastically more convenient. I seem to have somehow acquired nearly 1 imperial pound of documentation for every year I've been alive. That's just estimating based upon the weight of my panda file box next to my desk.
There's a lot in there, rental contracts, policy documents, w2 forms, that I might actually benefit from having scanned and digitally available on my computer. I feel that being able to search through these documents would have saved me some amount of trouble over the years.
Hell, if it were easy enough, I might actually scan all those receipts I bring home and then throw away.
You don't do much bureaucracy in your personal life (mortgages, moving around, children, or just keeping things as they are). I do similar things few times per year on average, and I don't do anything exceptional.
Plus living in a village, closest printing shop is maybe 10 minutes by drive. Scanner and good printer is a basic need in 2026.
I moved 5 times between 2015 and 2021 (air force), during which time I bought and sold houses at each move, have two kids in school, and I've never had to scan documents.
I have not once in my entire life had to scan 40 pages at once. I bet I've never done more than 15 at once.
For the once in a blue moon that I need to scan 40 double-sided pages I'd just go to my local print shop.
