Hi,
Guest checkout is a feature provided by commercial edition of HikaShop.
The "address" step requires the "login" step ; if you remove them, you won't have any user or address while creating the order.
The "guest checkout" in HikaShop allow to have a special "login" step where the user can create a "guest user", an entity without username or password but with an email and some addresses.
So yes it is possible to have a guest checkout, but it requires a commercial edition of HikaShop, like listed in our comparison page.
