I have a potentially really dumb question:

Why is a hardware wallet "Necessary" for cold storage?

Since the seed phrase to generate keys are the important thing, why does a body need to spend money on hardware wallet to store the seed phrase? (How to do that is another thing and I've already got that covered.)

I just haven't had the answer to that click yet. Help?

OK, here's where I'm currently still confused:

The hardware wallets are just for signing transactions. I get why they are useful. But...

I'm not understanding how you use an offline device to generate whatever it is that lets you control (send and receive) X amount of BTC, which are actions that require you to connect to the internet to push or receive info from the miners running the blockchain.

With an airgapped hardware wallet like the Coldcard, you move an SD card with the partially signed Bitcoin transaction from the computer to the wallet, sign it there, and then move the SD card with the signed Bitcoin transaction back to the computer to broadcast to get mined.
