Genuinely surprised by how even some established members of bitcointalk still suggest backing up wallets in digital format, completely ignoring the enormous mountain of incidents with lost coins due to the corresponded security risks of backing up likewise.
Well, it's OP who wanted a cheap portable wallet made out of a flash drive so most went along with his scenario. The utility of having an entire working wallet on a flash drive and not just the encrypted seeds you can extract when in need and import into the laptop or computer you would anyhow need to actually use the coins kind of fails to impress me.
But still, I assume most looked at it from the point of having around easy access to spendable coins, not about securing life savings, if the second I would 100% agree with you.
