Certainly. Mostly it started as a way to keep tax documents and receipts safe and easily findable.

It’s grown into a “huh, maybe this letter from <bank, school, insurance, charity, etc> is important, but it clutters the house less when ones and zeros”, so we scan it in.

Then when we need info, we can just search for the name of the sender, the date, account numbers, literally anything remotely legible in the document and get lightning fast results.
