This is not great in reality, as you're signing so many messages, dealing with a hardware wallet for each one is very tedious. We need the delegation NIP finished, so we can delegate to a less secure key from our cold keys.

Why would you have to deal with a hardware wallet for every single activity, it sounds like he’s saying generating the key with a wallet might be more secure? But I admittedly have no fucking idea lol.
Generating a key can be done just as well anywhere. I mean, there are different levels of random and entropy, but a hardware wallet doesn't inherently do this better than a python script.
A hardware wallet does it without the secret ever being online, on any machine thats online, etc.
When you go to sign a message to nostr, you'd have to ask the hardware to do it and go through it's whole process for signing, ' are you sure? ' etc.
