Why is it not a good solution for cold storage?
Discussion
For me purely as there is a hoy key involved in my setup. Tapsigners also need backing up in case they shit themselves. So this introduces more attack vectors. Nothing beats multisig seeds in steel geographically apart in my opinion.
That’s just me but everybody has different risk tolerance and situations. There is no one size fits all
I think Antonopolous describes it well here. https://youtu.be/nRts1VWkOXQ in general my main worry with a single hard ware wallet is that someone finds words and takes over it and there are simpler solutions to solving my single problem like having additional passphrase on top of my words. The multi sig brings extra complexity that requires much more effort in securing safely that emotionally are a bigger burden to me and I don’t feel confortável with it yet.

But, with the tapsigner you don’t have to use multi-sig. You can simple do single sig.
I don’t quite understand what you mean. I suppose you mean using a multisig with a coldcard and a tapsigner? I would never use tapsigner for my main multi sig. I totally loose stuff on the regular and would be relying heavily on the back up of that one. And what I dread is loosing one of the wallets on the multi sig
