Kinda the point of a wallet. It has several virtues that these new "mobile" wallets don't.
1. The things I have in the wallet are separable. 2. I can put non-digital information in it. 3. I can store untraceable currency in it. 4. It doesn't use batteries. 5. It is completely non-volatile. 6. It is completely secured from hacking. 7. I don't have to trust any third party with the contents of my wallet, ever. 8. The importance of 6 and 7 cannot be overstated.
and (9) my wages, earning, savings, etc... cannot be garnished at will by governing/crediting/banking parties as they see fit.
