Scanning and storing seems to be adding unneeded effort to your life. The only payoff seems to be that it is now electronic. Otherwise, BFD. Sometimes, upgrading the tech does not equate to upgrading your quality of life.
OK, you scan and store store stuff. Storing it takes about the same effort as filing the original. A year's worth of household/personal records is about 8 inches of file storage for me - and my records are fairly complicated. Those plastic file storage bins hold a foot and a half or so of records. Easy solution. After a few years they make a nice fire.
I like having hard copies around. I like knowing I have a piece of paper that I can hold up and say "You sent this to me ...." or something similar. I also like knowing that the only security risk comes from whoever sent me the bill/invoice/statement/whatever. Most things can be burned after a few years. Actually, most things should be burned after a few years. If the record has no use to you but could possibly be used against you, then why keep it?
Also, as a lawyer, I do dearly love electronic discovery because I can use all sorts of cool search tools to go spelunking through someone's/some company's past. On the other hand, there's no way that I want to make it easy for someone else to do that to me.
I do try to store medical records, legal records, and some account info forever. As in fireproof safe or safety deposit box. Those records benefit -me-. Everything else gets burned. Actually, shredded then burned. Shredded stuff burns so nicely.
