What happens if I delete my Apple Card?

What happens if I delete my Apple Card from my wallet? If you click Remove you get the message "Removing this card does not close your account and may impact your ability to manage your account if you do not have Apple Card on another device".

Does this mean that there is no other way to manage the account if you delete it?

Also, if you delete it can you restore it? Just curious since it's all managed from your Apple wallet.
