It wouldn't be for common transactions. We're talking about the kind of people who can pay 10 grands or more for a signing device.

I believe Bitcoin in my lifetime will be worth over $100M. I'm 42.
In that reality a single transaction will cost thousands on chain.
If everyone in the world wanted to ha e a single on chain TX it would literally take a lifetime for everyone to get one. Anyone on L1 in the future will have unfathomable wealth and those kinds of transactions will be done with convenience being the last thing on their list of priorities.
A beautiful signing device is not convenience. It's luxury. Perfect for the people you're describing.
Maybe the tap signers threw me off. I'm cashflow negative due to my large family and modest salary that isn't keeping up to the inflation, but I do have savings and it's 100% Bitcoin. I even withdrew all my RRSPs etc. that said, my cold storage is extremely locked down. I don't like anything wireless or unencrypted. Obviously the seedphrase must have an unencrypted copy to be truly robust but that need not be all in one place and should be in the best material for such things.
That said, you have beautiful products and I'm sure there will be many uses for a wallet or wallet like accessory.
