Hmm. So you can’t see any differences between a flash drive and cash?
If you withdrew your life savings in cash, that cash couldn’t become corrupted, unless by physical damage. Your life savings in cash would also be large enough that you wouldn’t be likely to lose it, or have the container it sits in easily stolen or accidentally smashed. You also are not very likely to forget or misplace the password to your cash.
Or, you could just use a credit card and have fraud protection.
If I had my life savings on a flash drive I think I could keep track of it pretty well. The nice thing about crypto wallets is you can replicate the secret key indefinitely. So, even if the drive is stolen you still have a password protected backup. If the cash is stolen, well, possession is 9/10s the law ;).
