Whenever somebody argues having nothing to hide I ask: 1) Where were you last night? 2) How much money is in your bank account? Do you have any debt? 3) What is your Debit Card PIN/account password/... 4) What is your address? Your families address? 5) Can I see your key? And so on. Everybody needs to proctect themselves and potentially others attached to them. There is a good reason for these questions being awkward…
And further, as a rule of thumb if someone is dealing in hypotheticals it means they don't have actual proof of harm. You'd never make an argument like this if you could point to Bob Jones and say "X happened to Bob Jones and it could happen to you."
