I dont think this is practical, you will pay for transfer fee just to pay clothes, food, water, appliances etc were as you can actually pay fiat without any additional fee. So far i don't know any mall or supermarket that accepts bitcoin here in my place.
Even in my country I haven't see any mall or supermarket that accepts bitcoin as a mode of payment and even if it does then also I think people would not be willing to spend their bitcoins as it can be time consuming to wait for transaction to get confirmed so people will prefer to use cash or debit/credit card for making payments.
