If you use Tails with LUKS encrypted volumes, I don't think using a password to guard Electrum wallet access is needed.
While using the computer, the encrypted volume will be unlocked and anyone with physical access could send funds if there's no password. So I'd recommend to use a password.
I'm saying this, because your audience is newbies
Especially for Newbies, it can't be repeated often enough to be secure, and use different passwords.
That being said: I use some wallets (inside a VM, of course) for low-value altcoin dust, and it's very convenient to send cents without the hassle of typing a password. I just wouldn't recommend it to anyone, by the time they understand what's at stake, they can decide this on their own.
