You should not be able to export your private key from any wallet UI

Just because I like to be difficult trying to think of any valid use case.

So what if my wallet has an “eject” button that will transfer all assets out of the wallet on all chains. Then it allows you to hypothetically print the private key so it’s available just in case someone accidentally transfers you assets to that wallet

Fwiw though this is why a 1/1 gnosis is useful so you can rotate wallets without changing public address

Wallets shouldn’t let you use the same private key on testnet that you are using on mainnet and the testnet one should be electable
