Id say for discounts is the only reason why they would choose to do so.
Yes they will use for discounts and also because the transactions made with bitcoins are irreversible.
Discounts would be good for beginnings , but im not sure for this irreversoble part . Im not sure how you think that irreversible transactions is good for everyday for bitcoins ? What if you go to store and you acidently pay guy 0.01 insted of 0.001 ?
So I think that bitcoin can only work in the field of directed assembly. For daily use bitcoin is clearly still too early to say. As for the discount, the bitcoin and so provides many benefits.
Yes for daily use the bitcoin is good for people, and it could be used all around the world. but you are right when you say its still early for everyday use of bitcoin. We can only hope that someday the bitcoin will be accepted as good currency to pay your bills.
Today, everywhere you can spend paying bills in digital format and without paper money without going to the cash desk. So I thought why not make the possibility of paying bills via bitcoin. Let them not make a decision on the only possible currency bitcoin, but allow the user to pay for it can be the same. I do not understand why not do this.
There are other problem that involve bitcoin as way of paying online or in person. You see, problem is that government cant know what is bought and sold online or in person. Government cant take there part and they cant trace it online if you have purchase some illegal things like weapons or drugs.
