And then you might think it would be a great idea to have a separate linux machine just for the purpose of signing transaction. So you do a minimal linux instalation, remove connectivity, get libreboot firmware. At that point you are basically tryimg to make a DIY signing device. A DIY hardware wallet, which is inevitably worse than a good hardware wallet, like Trezor. Because they thought of many more ways to harden it than you did.
