That's good for you, I believe you have skills that most people don't have, and I hope all technology becomes more accessible, which is good for everyone.

I trust my Tails with blocked communication drivers thus I can do encryption/decryption on any device, all I need is to insert to USB port my Tails flash drive.
Even if someone will get (somehow) my pgp encrypted SEED, which is hold in password manager, (again protected with hardware key) in persisted volume protected with composite password part of which on the security key, he still need to get my pin-protected (only 3 wrong attempts allowed) pgp card to decrypt it. Triple safeguard as you can see.
